Answer:

Explanation:

Calcium + Water → Calcium hydroxide + Hydrogen Gas

[Chemical Equation]

Ca (s) + 2(H2O) (l) → Ca(OH)2(aq) + H2 (g)

Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal.  Calcium is a member of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:

Ca(s)  +  2H2O(l)  ——>  Ca(OH)2(aq)  +  H2(g)

 

In the following demonstration, a chunk of calcium metal is dropped into a beaker of distilled water.  After a second or so, the calcium metal begins to bubble vigorously as it reacts with the water, producing hydrogen gas, and a cloudy white precipitate of calcium hydroxide.  The presence of the hydroxide is demonstrated by the addition of a few drops of phenolphthalein indicator, which turns the solution pink, indicating that the solution is basic.
