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.

$C_ t_o_t_a_l =[H_2A]+[HA^-]+[A^2^-]$

on rearrangements of the given equations

given K_a1 = 9.2 x 10^-4 & K_a2 = 4.3 x10^-5

for all pH values , pH = -log[H+] , calculate H+ and substitute in above equations along with K_a1 and K_a2

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