Copper Lab - AP Chemistry Lab Reports

After sulfuric acid was added to the beaker, copper was found as copper ions with a 2+ charge instead of the previous copper(ii) oxide form. 6. In the final step of the lab when the copper precipitate was washed, zinc ions were removed. The previous reaction that took place involved aqueous copper(ii) sulfate and solid zinc.

AN INVESTIGATION OF COPPER RECOVERY FROM A .

recovery, minor copper recovery and copper grade responses were optimized using JMP statistical software. Indicators of model inadequacies were noted but since the models predicted sensible solutions, inaccurate test ratios and un-modeled effects were hypothesized to be the source of the inadequacies. The model predicted 98 % copper recovery ...
