AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The pH of a salt formed from a strong acid and a weak base is less than 7 (acidic in nature).
Source: Acids, Bases and Salts, Section 2.4.2
The textbook explicitly states: "salts of a strong acid and weak base are acidic with pH value less than 7." Example: NH₄Cl (from HCl + NH₄OH). Examiners expect the pH value (less than 7) and the word "acidic" — both are needed for full credit.
