IB syllabus for first examinations To work out what is going on in a chemical reaction which involves redox we first need to identify the oxidation states of the species on either side of the reaction.
Once this is done we can deduce how many electrons have been transferred and produce half-equations. For example:In the reaction between chlorine and potassium iodide solution the products are iodine and potassium chloride solution. We can write an equation for the reaction:. The chlorine atoms start off in the zero oxidation state elementbut after the reaction they are now in the -I oxidation state the chloride ion.
This means that each chlorine atom has gained one electron. We can write the half equation:. Now the iodine species start off as iodide ions and end up as iodine element.
The change in oxidation state is from -I to zero. The balancing of equations for reactions in alkaline solution will not be assessed. Redox equations are constructed from half equations showing the reduction or oxidation of the species involved. By convention electrode potential half equations are written as reductions - electrons are added to the species being reduced on the left hand side of the equation:. Writing down the half equations in the correct form reduction for copper and oxidation for zinc.
We check to make sure that the electrons are balanced. In this case they are, and the equations can be added together directly. If the number of electrons on both sides are different then the half equations must be multiplied through by appropriate quantities to balance the number of electrons on both sides. These are the chemicals that cause the oxidation in a redox reaction. We call the reacting compounds in a reaction the reagents short form of the words reacting agents.
We consider that the removal of electrons from a species is oxidation and these electrons have to be taken away by another compound or species. This species that attracts the electrons is said to be the oxidising agent i.
Similarly the reagent that causes reduction in a redox reaction is said to be the reducing agent. The oxidising agent takes the electron and is itself reduced, the reducing agent loses the electrons and is itself oxidised. The first stage in identifying the oxidising and reducing agents in a redox reaction is to assign oxidation numbers states to the species in the reactant and the products.
The species that loses electrons is oxidised and this is caused by the species that gains the electrons. Hence the species gaining the electrons is the oxidising agent. The chlorine atoms start off in the zero oxidation state elementbut after the reaction they are now in the -I oxidation state the chloride ion This means that each chlorine atom has gained one electron.
Balancing redox equations Redox equations are constructed from half equations showing the reduction or oxidation of the species involved. Reducing agents Similarly the reagent that causes reduction in a redox reaction is said to be the reducing agent.
By the same logic the species losing the electrons is the reducing agent. The oxidising agent gets reduced The reducing agent gets oxidised.This page explains how to work out electron-half-reactions for oxidation and reduction processes, and then how to combine them to give the overall ionic equation for a redox reaction.
This is an important skill in inorganic chemistry. Don't worry if it seems to take you a long time in the early stages. It is a fairly slow process even with experience. Take your time and practise as much as you can. This topic is awkward enough anyway without having to worry about state symbols as well as everything else.
Practice getting the equations right, and then add the state symbols in afterwards if your examiners are likely to want them. How do you know whether your examiners will want you to include them? The best way is to look at their mark schemes.
You should be able to get these from your examiners' website. There are links on the syllabuses page for students studying for UK-based exams. You can split the ionic equation into two parts, and look at it from the point of view of the magnesium and of the copper II ions separately. This shows clearly that the magnesium has lost two electrons, and the copper II ions have gained them.
These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing! Any redox reaction is made up of two half-reactions: in one of them electrons are being lost an oxidation process and in the other one those electrons are being gained a reduction process. In the example above, we've got at the electron-half-equations by starting from the ionic equation and extracting the individual half-reactions from it.
That's doing everything entirely the wrong way round! In reality, you almost always start from the electron-half-equations and use them to build the ionic equation. In the process, the chlorine is reduced to chloride ions. You would have to know this, or be told it by an examiner.
In building equations, there is quite a lot that you can work out as you go along, but you have to have somewhere to start from! You start by writing down what you know for each of the half-reactions. In the chlorine case, you know that chlorine as molecules turns into chloride ions:. If you forget to do this, everything else that you do afterwards is a complete waste of time!
The left-hand side of the equation has no charge, but the right-hand side carries 2 negative charges. That's easily put right by adding two electrons to the left-hand side. The final version of the half-reaction is:. Now you repeat this for the iron II ions. You know or are told that they are oxidised to iron III ions.
Write this down:. The atoms balance, but the charges don't. There are 3 positive charges on the right-hand side, but only 2 on the left. You need to reduce the number of positive charges on the right-hand side. That's easily done by adding an electron to that side:. It is obvious that the iron reaction will have to happen twice for every chlorine molecule that reacts. Allow for that, and then add the two half-equations together. But don't stop there!! Check that everything balances - atoms and charges.

What Is The Total Ionic Equation For Potassium Iodide + Chlorine Potassium Chloride + Iodine?
From my understanding, since none of the products nor any of the reactants is aqueous, there shouldn't be a net ionic equation. However, my friend has proceeded with the problem as follows:. Technically you are correct. How can there be any ions when the reactants are not in aqueous medium? But here it is a matter of convention and maybe an illustration of how to write the ionic equations from molecular ones.
Likewise, if you have done balancing of redox reactionsyou might notice half of the reactions given to balance are completely impossible according to the laws of chemical combination. You'll always be at a loss when you overthink in chemistry, even if your argument is right. Taking it as just a convention would be a better idea.

Mithoron 4, 8 8 gold badges 32 32 silver badges 49 49 bronze badges. As for how the net ionic equation should be written, I think it's a matter of convention. This is a redox reaction, and sodium is not undergoing change in oxidation state, so that seems right to me. Hopefully somebody weighs in with a conclusive answer as to what the convention is.

This can be shown by looking at displacement reactions. When chlorine as a gas or dissolved in water is added to sodium bromide solution, the chlorine takes the place of the bromine.
Because chlorine is more reactive than bromine, it displaces bromine from sodium bromide.
The solution turns brown. This brown colour is the displaced bromine. The chlorine has gone to form sodium chloride. In this equation, the Cl and Br have swapped places:. This type of reaction happens with all the halogens. A more reactive halogen displaces a less reactive halogen from a solution of one of its salts. If you test different combinations of the halogens and their salts, you can work out a reactivity series for Group The slideshow shows what happens when chlorine, bromine and iodine are added to various halogen salts:.
Adding chlorine, bromine and iodine to halogen salts. Chlorine water is added to three solutions. The result of adding chlorine to the three solutions. Bromine water is added to three solutions. The result of adding bromine to the three solutions. Iodine water is added to three solutions. The result of adding iodine to the three solutions.
Redox reactions involve both oxidation loss of electrons and reduction gain of electrons. Halogen displacement reactions are redox reactions because the halogens gain electrons and the halide ions lose electrons. When we consider one of the displacement reactions, we can see which element is being oxidised and which is being reduced. We can see that the bromine has gained electrons, so it has been reduced.
The iodide ions have lost electrons, so they have been oxidised. Halogen displacement reactions The reactivity of the halogens — the Group 7 elements - decreases as you move down the group. Example When chlorine as a gas or dissolved in water is added to sodium bromide solution, the chlorine takes the place of the bromine.
