The sodium salt of cacodylic acid, a weak acid, has the formula NaO2As(CH3)2.3H2O. Its molar mass is 214.02 g mol-1 . A solution is prepared by mixing 21.40 g of this substance with enough water to make 1.000 L of solution. Then 50.00 mL of the sodium cacodylate solution is mixed with 29.55 mL of 0.100 M HCl and enough water to bring the volume to a total of 100.00 mL. The pH of the solution is 6.00. Determine the Ka of cacodylic acid.
