Finding ph from poh
Webp Kw = pH + pOH At 25 °C, the value of Kw is 1.0 × 10−14, and so: 14.00 = pH +pOH As we learned earlier, the hydronium ion molarity in pure water (or any neutral solution) is 1.0 × 10 −7 M at 25 °C. The pH and pOH of a neutral solution at this temperature are therefore: pH = −log [H 3 O +] = −log (1.0 × 10 −7) = 7.00 Web358K views 9 years ago pH Practice Acids & Bases. This video shows you how to calculate the pOH of a solution when given the [OH-] concentration. From the pOH you can then solve for the...

WebThe pH of a salt solution is determined by the relative strength of its conjugated acid-base pair. Salts can be acidic, neutral, or basic. Salts that form from a strong acid and a weak base are acid salts, like ammonium chloride (NH4Cl). Salts that form from a weak acid and a strong base are basic salts, like sodium bicarbonate (NaHCO3).
