Consider the methylamine buffer system. a. write the brønsted-lowry reactions for each of the conjugates reacting with water. write the equilibrium expression for each and determine the value of each equilibrium constant. b. calculate the ph of a solution prepared by mixing 1.33 g methylammonium chloride with 1.09 g methylamine and dissolving in enough water to make 250.00 ml of solution. c. calculate the ph of the solution from b. after 4.03 ml of 0.938 m hydrochloric acid are added. d. how many milliliters of 0.938 m hydrochloric acid should be added to 0.2204 g of methylamine to give a ph of 10.310?
