1. A 20.635 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 76.924 g of water. A 10.943 g aliquot of this solution is then titrated with 0.1038 M HCl. It required 29.30 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.

2.Calculate the pH at the equivalence point for the titration of 0.170 M methylamine (CH3NH2) with 0.170 M HCl. The Kb of methylamine is 5.0× 10-4.
