Back aboard the ship, in the botany lab, Mr. Sulu is performing a titration on a weak acid he has extracted from a native plant from the planet's surface. If he titrates this weak acid with sodium hydroxide, what value of pH does he expect before the titration begins, half-way to the equivalence point, at the equivalence point and after the equivalence point of his titration? Why would he get each of these pH values? (explain by indicating what species are in the beaker)
