Answer to Question #150311 in General Chemistry for Aisha

Question

If other acids beside acetic acid were present in vinegar how would they affect the results from the titration of vinegar with NaOH

Answer 1

Оn the titration curve of a mixture of 0.1 m hydrochloric acid and 0.1 m acetic acid with 0.1 m sodium hydroxide solution, there will be two titration jumps, the first one is not clearly expressed, and the second one is quite clearly visible.

this mixture can be titrated using two indicators: methylorange for the quantitative determination of hydrochloric acid and phenolphthalein for the quantitative total determination of both acids in the mixture.
