Energy is stored in the bonds of molecules. When these bonds split apart, the energy released can be used to do work. Breaking apart liquid water molecules into hydrogen and oxygen gas creates an enormous amount of energy, which can be turned into useful electricity to power our homes and cars.To break these bonds, some amount of energy is required to get the atoms in water molecules active enough to break apart from each other. At home, we can supply this energy with a battery. All batteries have two terminals, or ends: a positive terminal and a negative terminal. The water then connects these terminals, so energy can flow between them. As the electricity passes through the water, it splits the water!Pure water itself is not a good conductor of electricity, so for this experiment baking soda will be added to make the solution an electrolyte. An electrolyte is a part of a solution that can be broken up by electrolysis. Electro refers to energy and electricity and -lysis refers to splitting apart. Electrolytes are important both in batteries and in our bodies!
