The pH of water increase.
concentrated solution of NaOH and KOH have the pH value about 13.
our experiment on determining the pH of the ash solution gave us a pH of 11.26

Nothing because water is the only substance which has a PH of 7. Anything added to the water would change the PH unless you added pure water to it.
-log(1.0 X 10^-4 M KOH) = 4 14 - 4 = 10 pH KOH ----------------
Most metal hydroxides and oxides e.g. K2O and KOH
0.04 M KOH produces an OH- concentration of 0.04 M. Thus, the pOH is -log 0.04 = 1.4 and the pH will be 14 - 1.4 = 12.6
Yes, a concentrated solution of NaOH and KOH may have pH=14

4.83g of nitrous acid ( HNO2 )is added to water to make a final solution of 480.0ML.
