The three flasks shown below depict the titration of an aqueous NaOH solution with HCl at different points. One represents the titration prior to the equivalence point, another represents the titration at the equivalence point, and the other represents the titration past the equivalence point. (Sodium ions and solvent water molecules have been omitted for clarity.)
a. Write the balanced chemical equation for the titration.
b. Label each of the beakers shown to indicate which point in the titration they represent.
c. For each solution, indicate whether you expect it to be acidic, basic, or neutral.
