In an experiment to measure the pH values by using a universal indicator, a student found that the pH values of four given solutions A, B, C, and D are 10, 6, 2, and 14 respectively. The solution which will require the maximum volume of sodium hydroxide solution for complete neutralisation is solution :
(1) A
(2) B
(3) C
(4) D
Correct answer: (3) C
Explanation: The neutralization reaction is a reaction in which an acid reacts with a base and forms salt and water. As sodium hydroxide is a strong base, it needs a stronger acid to neutralize it. So, the solution C is the strongest acid as it has pH=2.
