Question

The PH of a solution of Hcl is 2.find out the amount of acid present in a litre of the solution ​

Answer 1

The solution is 10^-2 or 0.01M in HCl.

Step-by-step explanation:

meaning of pH is "power of hydrogen".

what is the molar concentration of a HCl solution with pH=2?

Let say pH=2

[H+]=10^-2M

HCL is a strong acid that dissociates completely:

[H+]=[HCL]

Therefore solution is 10^-2 or 0.01M in HCL.
