Reactions of Metals | S-cool, the revision website

Reaction of metals with water. Some metals also react with water, but like their reaction with oxygen, they react in different ways. We can observe the reaction of metals and water by placing the metals in a trough of cold water. Alternatively, we can observe the difference in reaction of metals using steam (hot water) instead of cold water.
