A 0.2536 g sample of the Cr-complex was thermally decomposed and the NH, released was collected in a 250 mL Erlenmyer flask containing 30.00 mL of 0.3065 M HCI solution and about 20 mL of deionized water. The solution was then titrated with standardized NaOH solution having a concentration of 0.2816 M. It required 11.92 mL of NaOH to reach the bromcresol green end point. Determine the %NI, in the sample.
