Determination of %NH3 in the coordination compound with the empirical formula: Cr,(NH3),CI, 1) A 0.2536 g sample of the coordination compound (CC) was thermally decomposed and the NH3 gas released was collected and reacted with 30.00 mL of 0.3065 M HCI solution (excess reactant). Next, the left over HCl in the solution was back titrated with standardized 0.2816 M NAOH solution. It required 11.92 ml of NaOH to reach the bromcresol green end point. Determine the %NH3 in the CC sample. Show your work below. NH3 (aq) + HCI (aq) → NH,CI (aq) (There is excess HCI left over from this reaction) HCI (aq) + NaOH Jaq) → Naci (aq) + H20 (I) (back titration reaction)
