WebpH of a solution is calculated using the formula (equation): pH = -log 10 [H + ] [H +] is the concentration of hydrogen ions in mol L -1 (mol/L or M) As the concentration of hydrogen … WebHow pH value is increased when HCl acid solution is diluted. If HCl solution has a high concentration such 0.1, 0.01 mol dm-3, pH value is increased by 1 when concentration is reduced from 10 times. When HCl concentration is too low like 0.00000001, 0.000000001 mol dm-3, pH value is not effected very much due to dilution of HCl acid. If HCl ...
