Concentration of an aqueous solution of ...

Concentration of an aqueous solution of weak acid, HA is 0.1 (M) . How many times this acid solution is to be diluted so that the degree of dissociation of HA becomes 2 times that of the initial solution?

Text Solution

Verified by Experts

`[H_3O^+]=0.01(M),pH=-log_(10)[H_3O^+]`
`=-log_(10)(0.01)=2`
