Please help! I know that I need an ICE table but I do not have a chemical equation.
Hippuric acid is a carboxylic acid, therefor the chemical equation could be written as
C9H9NO3====H+ + C9H8NO3-
Assuming in 0.120MM hippuric acid, x MM is converted to C9H8NO3- to reach the balance,
pKa=-log [H+][C9H8NO3-]/[C9H9NO3]=-log (10-3x+10-7)x/(0.120-x) =3.62
The equation can be simplified as
After calculation x=0.088 MM
Therefore in the balanced solution
[H+]= 0.088*10-3+10-7~8.8*10-5 M
