Calculate the alpha values for tartaric acid at pH values of: 0.00, 2.00, 4.00, 6.00, 8.00

Solutions

Expert Solution

Tartaric acid is weak diportic acid.

   

on rearrangements of the given equations

given Ka1 = 9.2 x 10-4 & Ka2 = 4.3 x10-5

for all pH values , pH = -log[H+] , calculate H+ and substitute in above equations along with Ka1 and Ka2

Therefore we will get all alpha values.. ( Note : Time is insufficient to calculate all alpha values)
