Question

which value is most likely to be the ph of a salt solution that is formed by the reaction of a strong acid and a weak base?
2.0
7.0
8.0
10.0

Explanation:

Step1: Recall salt - hydrolysis concept

When a strong acid and a weak base react, the salt formed undergoes hydrolysis in water. The cation of the salt (from the weak - base) reacts with water to produce hydronium ions ($H_3O^+$).

Step2: Determine solution nature

Since hydronium ions are produced, the solution is acidic. The pH of an acidic solution is less than 7.

Answer:

A. 2.0
