which value is most likely to be the ph of a salt solution that is formed by the reaction of a weak acid and…

Answer:

D. 8.7

Explanation:

Step1: Recall salt - hydrolysis concept

When a weak acid and a strong base react, the salt formed undergoes hydrolysis in water.

Step2: Analyze the hydrolysis reaction

The anion of the weak - acid part of the salt will react with water to produce hydroxide ions ($OH^-$) according to the reaction: $A^-+H_2O\rightleftharpoons HA + OH^-$, where $A^-$ is the anion of the weak acid and $HA$ is the weak acid.

Step3: Determine the pH of the solution

The presence of $OH^-$ ions in the solution makes the solution basic. A basic solution has a pH greater than 7. Among the given options, 8.7 is the only value greater than 7, so it is the most likely pH of a salt solution formed by the reaction of a weak acid and a strong base.
