Question

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)

A titration is performed with KOH and HCl. 0.0100 M HCl is used to titrate a 60.0 ml sample of a 0.0075M solution of KOH. What is the initial pH of the 60.0ml sample of KOH before any HCl is added? What is the pH after 20.0ml of the acid is added? What is the pH at the equivalence point? At the equivalence point, if all of the water is evaporated what mass of KCl is present?

Which is the best definition of the equivalence point for an acid-base titration? The equivalence point is when the concentration of the acid is equal to the number of moles of base. The equivalence point is when the solution turns from pink to clear. The equivalence point is when the solution turns from clear to pink. The equivalence point is when the number of moles of titrant added equals the number of moles of sample being titrated. O The equivalence point is when the volume of titrant added equals the volume of the solution being titrated. O O O O O
