Lab 6: Hardness

This lab is concerned with hardness, which is the amount of divalent metallic cations in the water.The primary causes of hardness are calcium (Ca +2) and magnesium (Mg +2) ions, but other metals such as strontium, ferrous iron, manganous, aluminum, and ferric iron can also contribute to hardness.Of these, ferric iron and aluminum ions tend to have little effect on hardness in natural waters ...

Limestone - Wikipedia

Limestone is a common type of carbonate sedimentary rock.It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes have likely been more ...
