advanced chemistry lab, a student prepared solutions of 0.1 citric acid (H3C6H507), 0.1 M lactic acid (HC3H5O3) and 0.1 M suituric acid (H2S04). Onfortunately, this advanced student heglected to label the samples or these acids! But all is not lost! The student recognizes that one of these is a monoprotic, one is a diprotic, and the other a triprotic acid. To determine the identity of the solutions, he decided to titrate the acids with 0.0500 M NaOH. Use the data he collected for his fırst titration to determine the identity of that acid.
