the ka of acetic acid is 1.76*x10^-5
what is the concentration of acetic acid for a solution that has ph of 2.45
what is the concentration of acetic acid for a solution that has ph of 2.45
Solution
CH3COOH<-----> CH3COO- + H+
pH = 2.45
-logH+ = 2.45
H+ = 10-2.45 = 3.55*10-3M =[CH3COO-]
Ka = [CH3COO-][H+]/[CH3COOH]
1.76*10-5 = (3.55*10-3)2/[CH3COOH]
[CH3COOH] = 0.716M
