A student says all salts are neutral. Which answer correctly evaluates this statement?
Answer and explanation
Correct answer: The statement is wrong because salts can be acidic, basic, or neutral
The nature of a salt depends on the acid and base from which it is formed and on the ions’ reaction with water. Sodium chloride, from a strong acid and strong base, gives an approximately neutral solution. Sodium carbonate is basic, whereas ammonium chloride is acidic because of hydrolysis. Therefore option A is correct. The other choices wrongly claim that every salt has pH 7, never dissolves, or never forms ions.
