We prepared an alkaline buffer through a series of precise steps. An equimolar solution of ammonia and ammonium chloride was created. This involved two solutions: Solution X, which was a 1 Molar NH3 solution, prepared by dissolving 1.703g of Ammonia in 100 ml of distilled water, and Solution Y, a 1 Molar NH4Cl solution, prepared by dissolving 5.9491g of Ammonium chloride in 100 ml of distilled water. Solution X and Solution Y were subsequently mixed to produce the alkaline buffer, with a pH of approximately 9.62.
