Answer:
HCOO- is a weaker base than CH3COO- .
Step-by-step explanation:
The options are:
HCOO- is a weaker base than CH3COO- . TRUE. The lower pKa the strongest acid. That means HCOOH is a stronger acid than CH3OOH. And, the strongest acid, the weakest base, thus, HCOO- is a weaker base than CH3COO.-
HCOOH is a weaker acid than CH3COOH . FALSE. The HCOOH is the weaker acid because has the lower pKa value.
HCOOH reacts with OH- while CH3COOH does not . FALSE. Both weak acid reacts with OH- producing its conjugate base and water.
CH3COOH completely ionizes in water . FALSE. A weak acid as CH3COOH partially ionizes in water.
CH3COOH reacts with OH- while HCOOH does not. FALSE. Both acids will react with OH-.
