Give the balanced equation. Cold and dilute NaOH on reaction with $$\text{Cl}_2$$ produce two compound A and B along with water. In which Cl oxidation number in A is $$-1$$ and B is $$+1$$.

Correct Answer: 0

Solution

PLACEHOLDER ANSWER - the answer is an equation. With cold, dilute alkali chlorine disproportionates to chloride and hypochlorite, $$\text{Cl}_2 + 2\text{NaOH} \rightarrow \text{NaCl} + \text{NaOCl} + \text{H}_2\text{O}$$. A is NaCl (Cl at $$-1$$) and B is NaOCl (Cl at $$+1$$).
