Answer

Brief Explanations:

To further analyze the two substances (covalent or ionic) dissolved in water, measuring the conductivity of the solution is a valid approach. Ionic compounds dissociate into ions in water and conduct electricity, while many covalent compounds (non - electrolytes) do not form ions in significant amounts and thus have low conductivity. Measuring weight (option b) does not help in distinguishing between covalent and ionic compounds as solubility (already known) and weight are not directly related to the type of bonding. Option a is incorrect as more analysis can be done. Option d is unwise and unsafe as the substances are unknown.

Answer:

C. I'd like to measure the conductivity of the solution
