Yes, calcium chloride will conduct electricity when dissolved in water. This is because calcium chloride is an ionic compound, meaning that it dissociates into positively charged calcium ions (Ca2+) and negatively charged chloride ions (Cl-) when dissolved in water. These ions are then able to move freely in the water, allowing them to conduct electricity. The ability of a substance to conduct electricity is known as its conductivity, and the conductivity of a solution increases with the concentration of ions in the solution. Therefore, the more calcium chloride that is dissolved in water, the better the solution will conduct electricity.
