Calculating the ph of a weak acid solution
WebJan 31, 2024 · A solution with a pH of 0 is known as a strong acid solution. Also, as the pH rises from 0 to 7, the acidity drops, and a solution with a pH of 14 is called a strongly … WebSep 21, 2024 · The pH will change as a result of many factors. Adjustment can be accomplished with different chemicals, depending on the tested pH. High pH can be lowered with liquid \(\ce{HCl}\) (unsafe material) or sodium bisulfate. The bisulfate anion is a weak acid and can dissociate partially in solution. To increase pH, use sodium carbonate.

Thus the product of the acid constant for a weak acid and the base constant for the conjugate base must be Kw, and the sum of p Ka and p Kb for a conjugate acid-base pair is 14. Equation 14.7.4 or 14.7.8 enables us to calculate the base constant of a conjugate base from the acid constant of the acid, and vice versa.
