Calcium and magnesium ions dissolved in water cause water hardness. Ethylenediaminetetraacetic acid (EDTA), shown on the right in its deprotonated form, is commonly used in a titration to determine the concentration of Ca 2+ and Mg 2+ ions in water because both ions form complexes with EDTA.
The Effects of Acid on Different Kinds of Metal | Sciencing
Both groups react with water and react even more vigorously with acids. These reactions yield hydrogen gas. With calcium, magnesium and lithium, the reaction is fairly gentle, but metals farther down in the group react violently, producing enough heat to set the hydrogen gas on fire and cause an explosion.
