Lactic acid (hc3h5o3) is a monoprotic acid with a ka value of 1.4 ✕ 10−4. (a) what volume of 0.15 m koh would need to be added to 25 ml of 0.086 m lactic acid to reach the equivalence point? (keep 2 significant figures) ml (b) at the equivalence point, would the aqueous solution be acidic, basic, or neutral? explain why. at the equivalence point, the solution will be . at this stage, all of the lactic acid in the solution will have reacted with the koh added, producing lactate ions (c3h5o3− ) and potassium ions (k + ) in the solution. the potassium ions will not affect the ph, but the lactate ions will make the solution .
