1. Propose a sketch of a titration curve for the titration of 0.1M H2SO4 (a diprotic acid; analyte) with 0.1M NaOH. (titrant). In a few sentences, justify the shape of your curve. Notice there is no volumes given, you do not need to be accurate like the questions above. I am looking for overall shape and justification of your graph.
