A chemistry graduate student is given 250. mL of a 0.90 M diethylamine NH) solution. Diethylamine is a weak base with K= 1.3 x 10 . What mass of (C2H5) NH2Cl should the student dissolve in the (C2H5) NH solution to turn it into a buffer with pH = 10.59? You may assume that the volume of the solution doesn't change when the (C, NH,Cl is dissolved in it. Be sure your answer has a unit symbol, and round it...
An analytical chemist is titrating 60.1 ml of a 0.2600 M solution of diethylamine ((CH), NH with a 0.4000 M solution of HNO,. The pK, of diethylamine is 2.89. Calculate the pH of the base solution after the chemist has added 26.7 ml of the HINO, solution to it.
