The overall dissociation of tartaric acid,H2C4H4O6, isrepresented below. The overall dissociation constant is alsoindicated.
H2C4H4O6<---->2H+ +C4H4O62-
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.)
D.) Calculate the value of the equilibrium constant, Kb, forthe reaction that occurs when solid Na2C4H4O6 isdissolved in water.
