How many litres of water must be added to 1 litre of an aqueous soluti

1.	How many litres of water must be added to 1 litre of an aqueous solution of hcl?
Answer» Initial pH = 1, i.e. [H+] = 0.1 mole/litre New pH = 2, i.e. [H+] = 0.01 mole/litre In CASE of dilution: M1V1= M2V2 0.1 ×1 =0.01 × V2 V2= 10 litre. Volume of WATER added = 9 litre.

How many litres of water must be added to 1 litre of an aqueous solution of hcl?

Answer»

Initial pH = 1, i.e. [H+] = 0.1 mole/litre

New pH = 2, i.e. [H+] = 0.01 mole/litre

In CASE of dilution: M1V1= M2V2

0.1 ×1 =0.01 × V2

V2= 10 litre.

Volume of WATER added = 9 litre.
