(A) What mass of KHSO4 is required to prepare 750 ml of 0.2 M KHSO4 solution?
(B) In one experiment, 25 ml of the unknown KOH solution is placed in a beaker. Added to the KOH solution in the beaker is 25 ml of water and a few drops of a suitable indicator. The KHSO4 is titrated into a dilute base.
(i) The volume of KHSO4 solution required to reach the equivalence point is 23.4 ml. What is the concentration of the initial unknown KOH solution?
(ii) What is the molar concentration of K+(aq) in the reaction mixture at the equivalence point?
