WebJan 30, 2024 · To find a concentration of hydronium ions in solution from a pH, we use the formula: (4) [ H 3 O +] = 10 − p H This can be flipped to calculate pH from hydronium concentration: (5) p H = − log [ H 3 O +] An acidic solution is one that has an excess of H 3 O + ions compared to O H − ions. WebJun 17, 2016 · 1 Answer Truong-Son N. Jun 17, 2016 You'll need two equations for this: pH = −log[H+] pH+pOH = 14 So, all you need to do is take the negative base-10 logarithm of the concentration of H+, and then subtract from 14. −log[H+] = pH → pOH = 14− pH If you recall, the autoionization of water works like this: H2O(l) ⇌ H+(aq) + OH−(aq)
