When examining the titrations of hydrochloric acid and acetic acid with naoh, we notice that the equivalence point of the hcl solution occurs at a ph of 7.00, while the hch3cooh solution has an equivalence point around ph 8.72. suppose that the hydrochloric acid solution initially contained 10 mol of hcl, while in the acetic acid solution, 10 mol of hch3cooh were present initially. at the equivalence point, which solution contains more naoh?
