How do boiling water and electrolysis compare
WebElectrolysis is chemical decomposition produced by electricity—in this case, the chemical you’re decomposing is water. The molecular formula for water is H 2 O, where H stands for the element hydrogen and O stands for the element oxygen. WebWater is a molecule that is a polar-covalent bond, so essentially there is a significant difference in the charges of the atoms that it is composed of (hydrogen=positive, oxygen=negative). The charge created by the two rods pulls the atoms in the molecules apart, so rather than boiling the water the process just pulls the water molecules apart ...
