10 mL of a solution of NaOH is found to be completely neutralised by 8 mL of a given solution of HCL. . If we take 20 mL of the same solution of NaOH, the amount of HCl solution (the same solution as before) required to neutralise it will be

- (a) 4 mL
- (b) 8 mL
- (c) 12 mL
- (d) 16 mL

Answer :

Since, 10 ml of NaOH requires 8 ml of HCl for neutralization,20 ml of NaOH will require:

(8 divided by 10)×20 = 16

Therefore,

Ans: (d) 16 ml
