Briefly explain whether the following procedural errors would result in either an incorrectly high or incorrectly low calculated percent Cu recovery for this experiment.

A) This solution was not basic when it was heated in part 3. ( in part 3 i convertedCu(OH)2 to CuO).

B) A slightly blue solution was decanted from Cu in part V. (in part 5 i reduced Cu(H20)6 ions with zink)

C) In part 5 the water in the beaker boiled away, exposing the evaporating dish to excess heat (same as above).
