Question

10 ml of a solution of NaOH is found to be completly 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 required to neutralise it will be

Answer 1

Answer:

Explanation:

Let molarity of naoh = x

Then molarity of hcl = 5x/4

Equivalent = equivalent

20x=5x/4×volume

Volume = 16 ml

Answer 2

Answer:

Since 10 ml of NaOH requires 8 mL of HCL, 20 ml of NaOH require 8 x 2 = 16mL of HCl Hence the answer id option d 16mL.
