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
