WebNov 23, 2024 · pH of pure water For pure water the concentration of [H + ] and [OH –] ions are same. That means, [H + ] = [OH –] So, from equation (i) we can write, K w = [H +] 2 As K w = 1.00 X 10 -14 mol 2 dm -6 [H +] 2 = 1.00 X 10 -14 mol 2 dm -6 Thus [H +] = 1.00 X 10 -7 mol dm -3 And pH = – log 10 [H +] = – log 10 (1.00 X 10 -7) So pH = 7 WebJul 25, 2015 · // ==UserScript== // @name AposLauncher // @namespace AposLauncher // @include http://agar.io/* // @version 3.062 // @grant none // @author http://www.twitch.tv ...
