WebA weak acid, HA, prepared by dissolving 0.015 mol of the acid in 1.0 L of water, is 3.9% ionized. Determine the pH of the resulting solution. Report your answer to two decimal places. WebThe pH of a 2.00 M solution of a strong acid would be equal to −log (2.00) = −0.30 . The higher pH of the 2.00 M nitrous acid is consistent with it being a weak acid and therefore not as acidic as a strong acid would be. The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem.

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 basic solution. When the pH drops from 14 to 7, the alkalinity drops. The strength of acids and bases depends on the number of H + and OH – ions formed. WebJan 31, 2024 · All acids of the generic formula HA have pKa. HA − ⇀ ↽ − H + + A −. The equilibrium constant for this simplified reaction can be written as. Keq = [H +][A −] HA Ka = [HA]Keq = [H +][A −] pKa = − logKa. The pK a becomes a simple measure of the strength of an acid.
