Answer these questions true or false: Hard water is the result of the presence high concentrations of Ca2+ and Mg2+ ions in water. If an ionic compound is insoluble, it can be removed from the solution as a precipitate. The presence of Ca2+ can be identified by adding carbonate ions (CO32-) ions. When an ionic compound dissolves, the ions come together in the solution. A centrifuge can be used to separate the solid precipitate from the liquid solution. The supernatant contains the ions that have precipitated.
