1.	How do you calculate pH of water from KW?
Answer» To FIND the pH you need first to find the hydrogen ion CONCENTRATION (or hydroxonium ion concentration - it's the same thing). Then you CONVERT it to pH. But in pure WATER, the hydrogen ion (hydroxonium ion) concentration must be equal to the hydroxide ion concentration....T (°C) Kw (mol2 dm-6) pH100 51.3 X 10-14 6.14
