What water is made of ??

How could you find out what it is made of

decomposition of water by electrolysis

Hydrolysis literally means reaction with water. It is a chemical process in which a molecule is cleaved into two parts by the addition of a molecule of water. One fragment of the parent molecule gains a hydrogen ion (H + ) from the additional water molecule. The other group collects the remaining hydroxyl group (OH − ).
