3.1.2.4. Chemical properties of minerals

Reactivity of a mineral

The reactivity is the ability of a mineral to cause certain chemical reactions.

For example, when calcite (CaCO3) reacts with hydrochloric acid (ClH), it decomposes giving off carbon dioxide (CO2).

Solubility of minerals

Solubility is the properties of some minerals that dissolve in water, such as gypsum.

In addition, some soluble minerals have a salty taste, such as halite (common salt) and silvin, which is somewhat more bitter.
