                                When calcium metal is added to water, it reacts vigorously to produce calcium hydroxide ($Ca(OH)_2$) and hydrogen gas ($H_2$). This chemical process, which is less violent than the reaction with alkali metals like sodium or potassium, creates an alkaline solution with numerous applications and health implications. The resulting solution, often called limewater, is an essential compound in many chemical and biological processes.
