Model Answer

(c) Exactly 7

Salts of a strong acid and a strong base are neutral, with pH value of exactly 7.

Source: Acids, Bases and Salts, Section 2.4.2

Explanation

The textbook directly states: "Salts of a strong acid and a strong base are neutral with pH value of 7." Example: NaCl (from HCl + NaOH). Remember — acidic salts (strong acid + weak base) have pH < 7, and basic salts (strong base + weak acid) have pH > 7.
