3 Example Of Hard Water. Water systems using groundwater as a source are concerned with water hardness, since as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply. Ferrous iron may also be present; oxidized to the ferric form, it appears as a reddish brown stain on washed fabrics and enameled surfaces.
If the solution fails to create lots of suds, you probably have hard. Any bathtub or sink in regular use will need regular cleaning to get rid of normal soap scum. This is because soap molecules are negatively charged on one end to help the molecule dissolve in water.
When you add soap to a solution.
Hard water can cause excessive scale buildup or deposits in pipes and appliances, which may reduce the life of your dishwasher, clothes washer or other appliances that regularly use water.
The longer water is exposed to a certain stone, the harder it will be. That's what you get when water evaporates and leaves calcium deposits behind. Hard water, water that contains salts of calcium and magnesium principally as bicarbonates, chlorides, and sulfates. Soft water: Soft water is surface water that contains very low concentration of ions or minerals, e.g., Rainwater and distilled water. Another unsightly issue is the appearance of those white, hard water spots. If you suspect that you have hard water, there is a low-tech way to test for it by shaking up a small amount of dish soap and water in a closed container.

Soft water: Soft water is surface water that contains very low concentration of ions or minerals, e.g., Rainwater and distilled water. While this may be a desirable feature in some cases, in others, it may be an issue. The water, which does not lather with soap, is called hard water. The scale may have a whitish color, and likely does not wipe away easily. For example, water from an underground aquifer will be harder than water from a river or lake.
Hard water also forms deposits that clog plumbing. It is tasteless and lathers easily with soap. As water percolates into deposits of calcareous, gypsum or chalk that are primarily composed of carbonates of magnesium or calcium, bicarbonates and sulfates, hard water is formed.
