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 HCl solution (the same solution as before) required to neutralise it will be

10 mL of a solution of NaOH is found to be completely neutralised by 8

1.	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 HCl solution (the same solution as before) required to neutralise it will be
Answer» 4 mL 8 mL 12 mL 16 mL Solution :The amount of HCl required will increase proportionately because the concentrations of both the NAOH and HCl solutions remain the same. The amount of HCl required will be ` 8 xx (20)/(10) = 16 mL` THUS option (d) is correct.
