The reaction mixture was then kept on ice. After addition of 270 μL of 50 mM HCl, the resulting derivative was analyzed immediately by LC/MS. NH3 was quantified by means of a standard curve obtained from the peak area of derivatized authentic NH3 in the negative ion mode. Measurement...
CuCl2 is an anhydrous, brown solid copper salt which is soluble in water and gives a brownish aqueous solution when concentrated. When diluted, the solution changes its colour to green and then blue. CuCl2 is formed when copper(II) oxide, CuO, is treated with hydrochloric acid, HCl: CuO +...
