how to use metallic character of calcium

A Study on the Precipitation of Calcium as Calcium-Fluoride.

calcium hydroxide is as strong a base as sodium hydroxide. Due to its more limited solubility, however, it does not form a concentrated solution. The oxitle of calcium is used to make mortar and plas ter and to raise the pH of acidic soils. Other properties
