3. Analysis of water chemistry - Wikipedia

   en.wikipedia.org/wiki/Analysis_of_water_chemistry

   An EPA scientist samples water in Florida Everglades. Samples of water from the natural environment are routinely taken and analyzed as part of a pre-determined monitoring program by regulatory authorities to ensure that waters remain unpolluted, or if polluted, that the levels of pollution are not increasing or are falling in line with an agreed remediation plan.

4. Water softening - Wikipedia

   en.wikipedia.org/wiki/Water_softening

   Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes

5. Wet chemistry - Wikipedia

   en.wikipedia.org/wiki/Wet_chemistry

   Graduated cylinders and beakers filled with chemicals. Wet chemistry is a form of analytical chemistry that uses classical methods such as observation to analyze materials. . The term wet chemistry is used as most analytical work is done in the liquid phase

6. dGH - Wikipedia

   en.wikipedia.org/wiki/DGH

   In water testing hardness is often measured in parts per million (ppm), where one part per million is defined as one milligram of calcium carbonate (CaCO 3) per litre of water. Consequently, 1 dGH corresponds to 10 ppm CaO but 17.848 ppm CaCO 3 which has a molar mass of 100.09 g/mol.

8. Hard water - Wikipedia

   en.wikipedia.org/wiki/Hard_water

   A bathtub faucet with built-up calcification from hard water in Southern Arizona. Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, [1] which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.

9. Total dissolved solids - Wikipedia

   en.wikipedia.org/wiki/Total_dissolved_solids

   When measuring water treated with water softeners, high levels of total dissolved solids do not correlate to hard water, as water softeners do not reduce TDS; rather, they replace magnesium and calcium ions, which cause hard water, with an equal charge of sodium or potassium ions, e.g. Ca 2+ ⇌ 2 Na +, leaving overall TDS unchanged [9] or even ...
