How would the intensity of light from the bulb change if you were to: a) Dissolve some additional CuSO4(s) in the CuSO4 solution?

The intensity of the light bulb increases

Explanation:

The conductivity of a solution depends on the concentration of ions in solution. This implies that, if the concentration of ions in solution is increased, the conductivity of the solution increases accordingly.

If we add more CuSO4(s) to the CuSO4 solution, the concentration of ions in the solution and consequently the conductivity of the solution increases.

Therefore, the intensity of the light bulb increases.

i'm wiling to try and you : )
