Wen chlorine is passed into a solution of potassium iodide, the iodide liberated required 18.6 cm^3 of 0.100 mol dm^-3 sodium thiosulfate.

1. Give the ionic equations for both reactions.

2. Describe the link between the number of chlorine and thiosulfate ions.

3. Calculate the volume of chlorine at RTP passed into the potassium iodide solution.

Hi there. First of all, it is iodine (not iodide) that is liberated from the reaction. Have you attempted the questions?
For 1, remember that chlorine displaces iodine in potassium iodide. The second reaction they are referring to is the iodine/thiosulfate titration.
