a)
To determine:
Whether tap water conducts electricity. To consider whether there are enough charges for ions to flow in a solution of tap water.
Introduction:
Electricity is a form of energy. It shows the flow of electric charge. The solutes have the ability to produce ions called electrolytes. Substance that does not conduct electricity, does not ionize in aqueous solution, and are also called as nonelectrolytes. A substance that conducts electricity, completely dissociates into ions in an aqueous solution. Ionic compound that dissolves in water is called strong electrolyte.
b)
To determine:
Whether pure water conducts electricity. To consider whether there are enough charges for ions to flow in a solution of pure water.
