Question

In your lab last week, you added concentrated NH,OH to the anhydrous CuSO, according to the following equation: If you started with a target weight that I assigned of 0.9000 grams of the copper sulfate, how many ml of 10.5 M ammonium hydroxide would you need to fully react to produce the maximum blue color complex? b. In your experiment, why was the concentrated ammonium hydroxide in sucha HUGE excess? (8 pts) 3. Give the correct answer with the correct number of significant figures and/or the correct uncertainty: (19 pts) A. 159.0 + 16.54 + 213 = B. 1.29 + 6.456 x 7.7754 = C. 138.14 + 24.1]/ [57.1 -24.6] D.
