   Wet chemistry techniques can be used for qualitative chemical measurements, such as changes in color (colorimetry), but often involves more quantitative chemical measurements, using methods such as gravimetry and titrimetry. Some uses for wet chemistry include tests for: [citation needed] pH (acidity, alkalinity) concentration

6. Hard water - Wikipedia

   en.wikipedia.org/wiki/Hard_water

   The permanent hardness of water is determined by the water's concentration of cations with charges greater than or equal to 2+. Usually, the cations have a charge of 2+, i.e., they are divalent. Common cations found in hard water include Ca 2+ and Mg 2+, which frequently enter water supplies by leaching from minerals within aquifers.
