Consider the below statements and identify the correct answer.
Statement-I: Salts of strong acid and a strong base are neutral with pH value of 7.
Statement-II: Salts of a strong acid and weak base are acidic with pH value less than 7.

Correct option is A

Sol: The correct answer is (a) Both the statements are true.

Analyze the given statements:

Statement I:

• True. Salts formed from the neutralization of a strong acid and a strong base are generally neutral, with a pH value around 7.
• For example, sodium chloride (NaCl) formed from hydrochloric acid (HCl, a strong acid) and sodium hydroxide (NaOH, a strong base).

Statement II:

• True.Salts formed from the neutralization of a strong acid and a weak base are typically acidic, with a pH value less than 7.
• This happens because the strong acid fully dissociates, while the weak base does not fully neutralize the acid.
• An example is ammonium chloride (NH4Cl), formed from hydrochloric acid (HCl, a strong acid) and ammonia (NH3, a weak base).

Both statements are correct.
