In one simplified version, the saponification of stearin gives sodium stearate. C 3 H 5 (O 2 C(CH 2) 16 CH 3) 3 + 3 NaOH → C 3 H 5 (OH) 3 + 3 NaO 2 C(CH 2) 16 CH 3. This process is the main industrial method for producing glycerol (C 3 H 5 (OH) 3). Some soap-makers leave the glycerol in the soap. Others precipitate the soap by salting it out ...
An antibubble is a droplet of liquid surrounded by a thin film of gas, [1] as opposed to a gas bubble, which is a sphere of gas surrounded by a liquid. Antibubbles are formed when liquid drops or flows turbulently into the same or another liquid. They can either skim across the surface of a liquid such as water, in which case they are also ...
Lestoil is a registered trade name of Clorox for a heavy-duty multipurpose cleanser product, used to remove extremely difficult laundry stains, dissolve water-based and oil-based paints, and clean grease, oil, paint, and adhesives from floors and surfaces. It was introduced as a dry cleaning fluid for laundry in 1933. [1]
Solubility is the property of a gas, liquid or solid substance (the solute) to be held homogeneously dispersed as molecules or ions in a liquid or solid medium (the solvent). In decompression theory, the solubility of gases in liquids is of primary importance, as it is the formation of bubbles from these gases that causes decompression sickness.
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 liquid water at high temperatures, (e.g. that approaching the critical temperature), the solubility of ionic solutes tends to decrease due to the change of properties and structure of liquid water; the lower dielectric constant results in a less polar solvent and in a change of hydration energy affecting the ΔG of the dissolution reaction.

Dettol antiseptic liquid is a product produced by the Dettol Brand for Reckitt. It is light yellow in color in the concentrated form but, as several of the ingredients are insoluble in water, it produces a milky emulsion of oil droplets when diluted with water, exhibiting the ouzo effect .
