A 21.928 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 72.517 g of water. A 11.823 g aliquot of this solution is then titrated with 0.1072 M HCl. It required 32.12 mL of the HCl solution to reach
the methyl red endpoint. Calculate the weight percent NH, in the aqueous waste.

During trial 2, what allowed you to determine that aluminum was the limiting reactant? check all that apply. all of the copper dissolved. all of the aluminum dissolved. the solution turned clear. the number of grams of copper(ii) chloride used in the reaction was greater than the number of grams of aluminum. the molar ratio of copper(ii) chloride to aluminum was greater than 3: 2, the equation’s molar ratio.
