Question

1) Consider the following mechanism:

1. ClO-(aq) + H2O(l) <=> HClO(aq) + OH-(aq) FAST

2. I-(aq) + HClO(aq) => HIO(aq) + Cl-(aq) SLOW

3. OH-(aq) + HIO(aq) => H2O(l) + IO-(aq) FAST

What is the role of HClO?

A. intermediate

B. catalyst

C. reactant

D. product

2) Consider the following mechanism:

Cl2 => Cl+ + Cl-

Cl- + H2S => HCl + HS-

Cl+ + HS- => HCl + S
