Problem- A 22.387 g sample of aqueous waste leaving a fertilizer manufacturer contains ammonia. The sample is diluted with 73.454 g of water. A 10.315 g aliquot of this solution is then titrated with 0.1079 M HCl. It required 29.41 mL of the HCl solution to reach the methyl red endpoint. Calculate the weight percent NH3 in the aqueous waste.
Answer showing how to make each solution will get rated
Consider the reaction: Cu^2+(aq) + 4NH3 (aq) -> Cu(NH3)4^2+(aq) Kf=2.1 x 10^13 If Ksp for Cu(OH)2 is 2.2 x 10^-20, what is the value of the equilibrium constant, K, for the reaction below? Cu(NH3)4^2+(aq) + 2OH -> Cu(OH)2(s) + 4NH3(aq)
