1.) Calculate the H3O+ ion concentrationand pH of a solution formed by adding 215 mL of .100 M acetic acid (CH3COOH) to 215 mL of .0500 M sodium acetate (NAOOCCH3).
2.) Calculate the molar ratio of aceitic acid and sodium acetate required to prepare 1.00 L of buffer solution with pH 3.8 (ka=1.75 x 10-5)
