Hard water content of 2+ and 3+ mineral metal ions is high. Most common hardness is result of Ca2+ and Mg2+ ions in ground- or surface water.
Soft water on the other hand, contains lower levels of calcium and magnesium. Rain water is soft.

Soft water contains low levels of dissolved minerals, mainly calcium and magnesium, whereas hard water contains higher levels of these minerals. Soft water is less likely to leave residue or build up deposits in pipes and appliances, while hard water can lead to limescale buildup and can affect the effectiveness of soaps and detergents.
Soft Water = Heart disease, Posion and Hypertension.. Hard Water = Tasty golden goodness with added calcium for added bone win. Enjoy your following water drinking days.. just not soft water, cause you will swallow it.. and die.
Hardness in water is defined as concentration of multivalent cations.
Multivalent cations are cations (positively charged metal complexes) with a charge greater than 1+. They mainly have the charge of 2+. These cations include Ca2+ and Mg2+, but Fe2+/3+ and Mn2+ are also common 'hardness' ions.
They all are possible to be deposited (by precipitation) with carbonate, sulfate and hydroxide ions.
Hard water has more minerals in it.
Hard water is water that has high mineral content (in contrast with "soft water")
Water is of two types i.e hard water and soft water. Soft water is the water that easily lather with soap while hard water does not lather with soap.
Pure water is a water without any impurities; soft water doesn't contain calcium and magnesium carbonates.
Boiling hard water does not make it soft. Boiling water only removes some impurities and kills bacteria, but it does not change the mineral content that makes water hard. To soften hard water, a water softener system is needed.
Hard water is generally a weaker solvent compared to soft water. This is because hard water contains minerals like calcium and magnesium, which can reduce its ability to dissolve other substances effectively. Soft water, on the other hand, lacks these minerals and is better at dissolving substances, making it a more efficient solvent.
Hard water has a lower foaming capacity compared to soft water because the presence of minerals such as calcium and magnesium interferes with the formation of soap lather. Soft water, on the other hand, allows for more effective lathering with soap due to the absence of these minerals.
River water is generally considered soft water because it contains low levels of minerals like calcium and magnesium. Hard water typically comes from sources like groundwater or wells, where it has passed through mineral-rich rocks.
Soft water typically has a pH level between 6.5 to 8.0. However, the exact pH level can vary based on the source and any treatment processes the water has undergone.
