It has similar solvent properties to acetone but boils at a higher temperature and has a significantly slower evaporation rate. [12] Unlike acetone, it forms an azeotrope with water, [13] [14] making it useful for azeotropic distillation of moisture in certain applications. Butanone is also used in dry erase markers as the solvent of the ...
The following compounds are liquid at room temperature and are completely miscible with water; they are often used as solvents. Many of them are hygroscopic.
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

Water conditioners are formulations designed to be added to tap water before its use in an aquarium. [1] [2] If the tap water is chlorinated then a simple conditioner containing a dechlorinator may be used. These products contain sodium thiosulfate which reduces chlorine to chloride which is less harmful to fish.
In general terms, any solvent that contains a labile H + is called a protic solvent. The molecules of such solvents readily donate protons (H +) to solutes, often via hydrogen bonding. Water is the most common protic solvent. Conversely, polar aprotic solvents cannot donate protons but still have the ability to dissolve many salts. [1] [2]
