A `50 ml` solution of `pH=1` is mixed with a `50 ml` solution of `pH=2`. The `pH` of the mixture will be nearly

50 ml of solution of pH = 1 is mixed with 50 ml of solution of pH = 2. The pH of the mixture is nearly :

When 200 ml of an aq. solution of HCl (pH=2) is mixed with 300 ml of an aq. solution of NaOH (ph = 12), the pH of the resulting solution is

4 ml of HCl solution of pH = 2 is mixed with 6 ml of NaOH solution of pH=12 . What would be the final pH of solution ?( log 2 = 0.3 )
