Question

In addition to being a Bronsted-Lowry, acetate is an Arrhenius base. When acetate is dissolved in water, the concentration of hydroxide is increased. Complete the following reversible reaction. Then identify conjugate acid-base pairs. Hint: think of water as HOH.CH3COO-(aq) + H2O(l) <---->

Answer 1

CH₃COO ⁻ + H₂O ⇔ CH₃COOH + OH⁻

Base Acid Conjugated weak acid Conjugated base

Step-by-step explanation:

Acetate is a Bronsted-Lowry base because it can accept a proton from water.

This makes the solution be basic, because it release hydroxides.

CH₃COO ⁻ + H₂O ⇔ CH₃COOH + OH⁻

Base Acid Conjugated weak acid Conjugated base

Water becomes an acid, because it can release a proton, following the Bronsted-Lowry theory.
