The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
In-tank toilet cleaners (also known as toilet water tablets or drop-in toilet bowl cleaners) are tablets or cartridges that add chemicals to toilet tank water to reduce toilet bowl stains. They are commonly used to prevent toilet bowl stains from calcium , limescale , mold , etc. [ 1 ] Most contain chlorine bleach as its main active ingredient ...
A dense non-aqueous phase liquid or DNAPL is a denser-than-water NAPL, i.e. a liquid that is both denser than water and is immiscible in or does not dissolve in water. [1]The term DNAPL is used primarily by environmental engineers and hydrogeologists to describe contaminants in groundwater, surface water and sediments.
However, during the defluoridation process the hydroxyapatite dissolves, and increases the pH and phosphate ion concentration which makes the defluoridated water unfit for drinking. [46] Recently, a ″calcium amended-hydroxyapatite″ defluoridation technique was suggested to overcome the phosphate leaching from hydroxyapatite. [ 46 ]
A sodium ion solvated by water molecules. Solvations describes the interaction of a solvent with dissolved molecules. Both ionized and uncharged molecules interact strongly with a solvent, and the strength and nature of this interaction influence many properties of the solute, including solubility, reactivity, and color, as well as influencing the properties of the solvent such as its ...
Other variants, such as a solid tablet in a water-soluble wrapper, to be placed in the toilet's water tank, were introduced later. [3] In 1960, O’Hare sold Ty-D-Bol Chemical to its other executives for less than $100,000; independently he pursued an assortment of inventions - various detergents, a swimming pool chlorinator, a water softener.

An alternative to the Stiff diagram is the Maucha diagram. Stiff diagrams can be used: 1) to help visualize ionically related waters from which a flow path can be determined, or; 2) if the flow path is known, to show how the ionic composition of a water body changes over space and/or time. Example of a Stiff diagram
A suspension is a heterogeneous mixture in which the solid particles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium. [1] The internal phase (solid) is dispersed throughout the external phase (fluid) through mechanical agitation , with the use of certain excipients or suspending ...
