K=4.60x10-8
A.) What volume of 0.250 molar KOH is required to neutralize completley a 5.00x10-3 mole sample of pure tartaricacid?

B.) Give the Equations representing the first and second dissociations of tartaric acid. Calculate the value of the firstdissociation constant, K1, for tartaric acid if the value of the second dissociation constant, K2, is4.60x10-5.

C.) To a 0,015 molar solution of tartaric acid, a strong acidis added until the pH is 0.5. Calculate the[C4H4O6 2- ] inthe resulting solution. (Assume the change is volume isnegligible.)
