Select the statements that are correct with respect to waste disposal in the Electrochemical Cells Experiment. (Select all that apply.)

a. Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.
b. Rinsings from the half-cell module can be flushed down the sink.
c. Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.
d. The contents of the half-cell module should be disposed of in the waste container in the hood.
e. No waste will be generated during this experiment.
f. The electrodes should be discarded in the proper jar.

A. Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.

C. Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.

D. The contents of the half-cell module should be disposed of in the waste container in the hood.

Explanation: An electrochemical cell is a cell that has the capability of producing Electric energy from chemical reaction (voltaic cells) or using Electric energy to make chemical reactions to take place(electrolytic cell). For a proper or effective waste disposal in an electrochemical cell the following options are correct.

Dilute copper and ascorbic acid solutions should be disposed of in the waste container in the hood.

Metal and graphite electrodes should be rinsed with water, dried, and returned to their positions on the lab bench.

The contents of the half-cell module should be disposed of in the waste container in the hood.

c) always accurate
