Ha and a- chemistry
WebSo the added H+ reacts with A- to form HA. So for the particulate diagrams, this added H+ is going to react with one of the A minuses present in the buffer solution. So the H+ and the A- form an HA. So we're gonna go from five HAs to six … WebNov 13, 2024 · If we add 0.2 mol of sodium hydroxide to a solution containing 1.0 mol of a weak acid HA, then an equivalent number of moles of that acid will be converted into its base form A –. The resulting solution will contain 0.2 mol of A – and 0.8 mol of HA.
