types of hard water. hard water is water containing high amounts of mineral ions. the most common ions found in hard water are the metal ions calcium (ca 2 +) and magnesium (mg 2 +) though iron aluminum and manganese may also be found in certain areas.these metals are water soluble meaning they will dissolve in water.

reactions between aluminum and lime. a discussion started in 2005 but continuing through 2017. 2005. q. i have a question when our aluminum tank coverings for upright storage tanks were exposed to lime from a cement plant they all turned black. what is the reaction here and what if anything can we do to protect the tank coverings?
20051228&ensp·&enspthe easiest time to remove calcium hydroxide efflorescence is before it combines with carbon dioxide. up to this time it will dissolve in water so pressure washing or wet scrubbing will put it in solution with water so it can be rinsed away. you must be careful to rinse the surface with fresh water so that no residue is left to dry on the
to remove manganese from water with a filter a high ph reading and a sufficient oxygen content are necessary to ensure precipitation. although different filter media have different requirements in most cases a ph greater than 8 is need for effective manganese removal.
what's the best way to remove calcium from well water? general discussion. i have a water well that i think was a little too shallow and it is causing a calcium problem. i can freeze the water to ice and that seems to cause the calcium to bond together but would there be a better way to remove the calcium from the water? but what about

2019109&ensp·&ensp$begingroup$ this answer goes into lots of detail but it seems to focus on why calcium carbonate won't dissolve in the first place. (which to be fair was the focus of the original question.) what about: why does calcium carbonate precipitate out when you dissolve calcium chloride and sodium carbonate in water?
calcium oxide is a compound of calcium and oxygen and has the formula cao. it is very basic (alkaline) and will react with water to form calcium hydroxide ca(oh)2 which is a strong base.
calcium oxide is a dehydrating molluscicide. what are the environmental effects of calcium in water? calcium is a dietary requirement for all organisms apart from some insects and bacteria. calcium carbonate is a building stone of skeletons of most marine organisms and eye lenses.
