The hard water from Edwards aquifer will likely contain dissolved calcium trioxocarbonate (iv) or magnesium and calcium tetraoxosulphates (iv).
<h3>What is hard water?</h3>
Hard water refers to water that contains dissolved minerals in it.
The hardness of water may be temporary or permanent hardness.
Temporary harness is caused by trioxocarbonates of calcium in water.
Permanent hardness is caused by magnesium and calcium tetraoxosulphates.
Thus, the hard water from Edwards aquifer will likely contain dissolved calcium trioxocarbonate (iv) or magnesium and calcium tetraoxosulphates (iv).
