calcium metal in water observations

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.

Lab 10 - Solubility Product for Calcium Hydroxide

The concentration of Ca(OH) 2 (s) does not appear in the equilibrium constant expression because it is always present as the pure solid (activity is 1), no matter how much or how little of it is present. A saturated solution of Ca(OH) 2 can be prepared by the reaction of calcium metal with water.
