also began to admit heat once the sodium borohydride was added. The substance was allowed to stir for two more minutes and then we let it cool to room temperature for about ten minutes so that the precipitate could dissolve. However‚ while cooling bubble began to form at the top of our substance. After cooling‚ we added approximately 10.0 mL of hot water (~76.5 ˚C) and allowed the solution to boil on a hot plate; adding the hot water also caused the solution to become a clear pale yellow solution
