Poh relation to ph
WebpKw = pH+pOH p K w = pH + pOH At 25 °C, the value of Kw K w is 1.0×10−14 1.0 × 10 − 14, and so: 14.00 = pH+pOH 14.00 = pH + pOH As we learned earlier, the hydronium ion molarity in pure water (or any neutral solution) is 1.0×10−7M 1.0 × 10 − 7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: WebMay 12, 2016 · The pH and pOH of a substance will always total 14. Explanation: pH means "power of hydrogen" and is a measure of the hydrogen ion concentration. If the concentration of H + ions is 10−1, the pH is 1, and the pOH is 13. 10−1 = …
