The pH of z solution at `25^(0)C` is `2`. If its pH is to be changed to 4, conc. of `H^(+)` of the original has to be

The pH of an aqueous solution at 25^(@)C is 6.1 its p(OH) is :

The pH of a solution is 2. Its pH is to be changed to 4. Then the H^+ concentration of original solution has to be:

The pH of the solution is 3.0 if its pH is changed to 6.0 then the [H^+] of the original solution has to be :

The pH value of solution is 2. If its pH value is to be doubled then the H+ ion concentration of the original solution has to be decreased by :

pH of a solution is 4. [H^+] is

pH of a solution solution at 25^(@)C is 2 . If the pH is to be doubled , the hydronium ion concentration of the solution should be

The pH of an solution is 4.0, its pOH will be

If pH of a solution is 4, its [H^+] is
