You must recognize what is going on here.
CO3^-2 + H^- ==> HCO3^- + H2O . When the indicator turns at the first equivalence point, this is the reaction that has taken place. Technically, the highest concn will be water; however, that isn't one of the answers. After looking at the equation, you say.......
