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

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.

so what is the problem with your lab report and whats the subject of the lab report? i will you
