1. A chemist, , wishes to prepare 100.0 mL of a buffer of pH 10.0000 using the base methyl amine, CH3NH2, ánd its salt, CH3NH2, and its salt, CH;NH3CI. (a) What should be the ratio of base to salt to obtain a pH of 10.00? (b) If he makes the solution 0.05000 M CH3NH2, how many moles of methyl ammonium chloride should he add to get the desired pH ? K = 5.00 x 10*
