1. Calculate the pH of a solution containing 0.0746 M nitrous acid (HNO2) and potassium nitrite.
(KNO2) 0.253 M Ka = 4.5 x10^-4 in 1.0 L of solution
2.What is the pH of a buffer that is 0.012 M in lactic acid [CHaCH(OH)COOH] AND0.050M in sodium lactate [CH CH(OH)COONa]? For lactic acid Ka = 1.4x10^-5.
