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

Solution

When an acid reacts with a base and forms salt and water it is known as a neutralization reaction. Stronger the acid stronger the base required to neutralize it. So, the maximum amount of sodium hydroxide is required in "C" solution as it is the strongest acid among the following options.

Hence, the correct answer is option 3.
