22/10/2019· Water systems using groundwater as a source are concerned with water hardness, since as water moves through soil and rock it dissolves small amounts of naturally-occurring minerals and carries them into the groundwater supply.Water is a great solvent for calcium and magnesium, so if the minerals are present in the soil around a water-supply well, hard water may be delivered to homes.

Calcium Hypochlorite quickly forms hypochlorous acid (the killing form of chlorine) in water. It is used in water treatment as a general biocide. Calcium hypochlorite is used by many paper conservationists to bleach archival papers, and it is used as an oxidizing agent to reduce the effects of foxing.
Fluoride: 1. What are fluorides? - GreenFacts
1.2 What are fluorides used for in industry? Fluorides are important industrial chemicals with a nuer of uses but the largest uses are for aluminium production, drinking water fluoridation and the manufacture of fluoridated dental preparations. Hydrogen fluoride (HF) is a colourless, pungent liquid or gas that is highly soluble in organic solvents (e.g., benzene) and in water.
Magnesium Chloride | Solubility of Things
The main appliion of magnesium chloride is production of magnesium metal. This is done by the precipitation process for which the formula is given in the common reactions section. Magnesium chloride is also used for a variety of other appliions like the manufacture of textiles, paper, fireproofing agents, cements and refrigeration brine, and dust and erosion control.
What is the reaction equation for phosphate ion and …
Sodium phosphate is soluble in water. Normally, compounds of the phosphate ion are insoluble, the exceptions being salts of NH4+ and the alkali metal ions (the sodium ion is one).

(K a for HCO-3 = 4.8 x 10-11 << K a for HSO 4-= 1.1 x 10-2) Thus, calcium carbonate is much more soluble in acidic solution, whereas the solubility of calcium sulfate is only slightly affected. The effect of pH on solubility can be used to separate metal ions by .
solubility - What does it mean to say that a strong base is …
Some strong bases like calcium hydroxide aren''t very soluble in water. That doesn''t matter - what does dissolve is still 100% ionised into calcium ions and hydroxide ions. Calcium hydroxide still counts as a strong base because of that 100% ionisation.
How To Remove Calcium And Magnesium From Water? …
Such water is described as “hard water” with the level of hardness depending on the concentration of calcium and magnesium. In this article, We focus on hard water, and how to remove calcium and magnesium ions in it.

Solubility and Complexation Equilibriums
Most metal chloride salts are soluble in water; only Ag +, Pb 2+, and Hg 2 2+ form chlorides that precipitate from water. Thus the first step in a qualitative analysis is to add about 6 M HCl, thereby causing AgCl, PbCl 2, and/or Hg 2 Cl 2 to precipitate.

What is Calcium Carbonate? (with pictures) - wiseGEEK
4/8/2020· This dissolved calcium carbonate forms calcium bicarbonate, which then precipitates out of solution to become an insoluble solid (it is only soluble in a carbonic acid, not pure water). This precipitation is what forms the stalactites and stalagmites that form within caves (and the lime scale around your bathtub that is so hard to scrub off).
