Ph of polyprotic acids
Web(This is because the maximum pH that can be achieved with 0.100-M NaOH is 13.) The titration curve for the reaction of a polyprotic base with a strong acid is similar, but inverted on the pH scale. The initial pH is high; as acid is added, the pH decreases in steps if the successive p Kb values are well separated.

WebpH-meter. When the diprotic acid was being titrated with sodium hydroxide the pH-meter was. used to collect the data. The data were obtained from the experiment through titration was then put into an Excel. spreadsheet and the pH was graphed to show the progression of the basicity as the sodium. WebSeveral important acids can be classified as polyprotic acids, which can lose more than one H + ion when they act as Bronsted acids. Diprotic acids, such as sulfuric acid (H 2 SO 4 ), carbonic acid (H 2 CO 3 ), hydrogen sulfide (H 2 S), chromic acid (H 2 CrO 4 ), and oxalic acid (H 2 C 2 O 4) have two acidic hydrogen atoms.
