Chemistry QUESTION
(a) Chlorine is an important industrial chemical used to make bleach.
Cl2 + 2OH– Cl– + ClO– + H2O Equation 3.1.
(b) Chlorine is mixed with sodium hydroxide.
At equilibrium the concentration of OH– is 1.00 × 10–5 mol dm–3 and the concentration of Cl2 is 1.24 × 10–6mol dm–3.
Find the concentration of Cl– ions.
The concentration of water is not included in the expression for Kc.
I’m really confused on working this out this all the information in the question.
Thank you!

The problem's text lacks the necessary value of Kc (relative to equation 3.1) to determine the concentration of Cl^– ions.
Please supply the value of Kc, and I will assist you in calculating the precise concentration of Cl^– ions.
Note that the correct way to write equation 3.1 is as follows Cl2 + 2OH- ==> Cl- + ClO- + H2O

As above, you will need to know the value of Kc.
Another thing worth being aware of is the concentration of [ClO^-] ions. Looking at the equation, what do you notice about the ratio of Cl^- ions formed to ClO^- ions formed?
