I am doing an experiment that involves testing the conductivity of three different chemical compounds dissolved in water. I will be testing Potassium Chloride, Calcium Chloride and Zinc Chloride. All three will be of equal concentration. Is there any way to determine the conductivity of different chemical compounds dissolved in water? Out of these three chemical compounds, which one will be the most conductive, and why? Is there any correlation between reactivity and conductivity of chemical compounds?
