Question

20 mL of a solution of NaOH is found to be completely neutralised by 6 mL of a
given solution of HCI. if we take 25ml of the same solution of NaOH, then what amount of HCI solution ( the same solution as before) required to neutralized it?

​

Answer 1

Explanation:

20=6

1=6/20

25=6×25/20

=6×5/4

=3×5/2

=15/2
