If the concentration of the hydrogen ions, increase then the solution would become more and more acidic and thus have a lower pH value than compared to the pH value before at the 1.0 X 10^-2 M.

Could the mechanism for the reaction of crystal violet with sodium hydroxide consist of one elementary step? Explain.
kondaur [170]

Answer:

Yes

Explanation:

Let's write the reaction as

CV⁺+ OH⁻ ⟶ CVOH

The reaction is first order in [CV⁺] and in [OH⁻], so the rate law is

rate = k[CV⁺][OH⁻]

A bimolecular collision between a crystal violet ion and a hydroxide ion as an elementary step would predict the observed rate law.

However, other plausible mechanisms may predict the same rate law.
