Question

Quizplus · Accepted Answer

Calcite is a mineral that readily dissolves in water, especially in acidic or slightly acidic conditions. This is because calcite is a carbonate mineral and reacts with acids to form dissolved calcium ions and bicarbonate ions, which are soluble in water. On the other hand, clay minerals, silica, and feldspars are all aluminosilicate minerals with low solubility in water, although they may weather and break down over time.
