Question

The student observes that the blue color becomes less intense as the cell operates. State one inference that the student can make about the concentration of the Cu2+ ions based on the change in intensity of the color of the Cu(NO3)2(aq) solution as the cell operates.

Answer 1

The concentration of Cu^2+ is decreasing

Step-by-step explanation:

As time progresses, it will be observed that the intensity of blue colour gradually fades. This blue colour is as a result of the presence of Cu^2+ ion.

As the concentration of this ion decreases, the blue colour of the solution gradually fades as the cell operates.
