Question

This question deals with waste disposal in the Solutions and Spectroscopy experiment. What should be done to waste solutions containing copper ion? (Select all that apply.) a. It should be flushed down the sink. b. It should be dumped in a beaker labeled "waste copper" on one's bench during the experiment. c. No waste will be generated in this experiment. d. It should be disposed of in the bottle for waste copper ion when work is completed. e. It should be returned to the bottle containing 0.5 M copper sulfate solution.

Answer 1

Answer:

b. It should be dumped in a beaker labeled "waste copper" on one's bench during the experiment.

d. It should be disposed of in the bottle for waste copper ion when work is completed.

Explanation:

Solutions containing copper ion should never be disposed of by dumping them in a sink or in common trash cans, because this will cause pollution in rivers, lakes and seas, being a contaminating agent to both human beings and animals. They should be placed in appropriate compatible containers that can be hermetically sealed. The sealed containers must be labeled with the name and class of hazardous substance they contain and the date they were generated.

It never should be returned to the bottle containing the solution, since it can contaminate the solution of the bottle.

In the Solutions and Spectroscopy experiments there is always wastes.
