Explain What Observation Supports The Formation Of Cu2 + Ions
What observation supports the formation of the Cu2+ ions in the solutions? The 15mL of nitric acid and the heat from the Bunsen burner supports the formation of the Cu2+ ion. Why was it important to perform this reaction in the fume hood? It is important because the chemicals produce a toxic gas. Is there any copper metal left after you have completed this step? If not, where is the copper? No, there is no copper left. It dissolved in the nitric acid solution. Did you initially observe the formation of a precipitate that re-dissolved when more aqueous ammonia was added? No, eventually the solution changed to a blue color. What is the color of the complexion? [Cu(NH3)4](OH)2(aq), in your solution? The color of the complexion is blue in the
