WebSep 3, 2024 · Thanks to @Maurice we know that 2 pH = 0.01 mol/L). We can use that in @Ivan Neretin comment who says to divide 1 L of HCl by 12 (the molarity of 37% HCl), then divide that again by 100. This concurs with the comment by @Mithoron who suggests diluting the HCl 1200 times. WebExample 2: A 0.010 M solution of hydrochloric acid, HCl, has a molarity of 0.010 M. +This means that [H ] = 1 x 10-2 M. The pH of this aqueous solution of H+ ions is pH = 2.
