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.
Hexane (/ ˈ h ɛ k s eɪ n /) or n-hexane is an organic compound, a straight-chain alkane with six carbon atoms and the molecular formula C 6 H 14. [ 7 ] Hexane is a colorless liquid, odorless when pure, and with a boiling point of approximately 69 °C (156 °F).
Specific gravity is defined as the density of the solvent divided by the density of water at the same temperature. As such, specific gravity is a unitless value. It readily communicates whether a water-insoluble solvent will float (SG < 1.0) or sink (SG > 1.0) when mixed with water.
The tables below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at one atmosphere pressure. Units of solubility are given in grams of substance per 100 millilitres of water (g/(100 mL)), unless shown otherwise. The substances are listed in alphabetical order.
Such substances are said to be miscible (etymologically equivalent to the common term "mixable"). The term is most often applied to liquids but also applies to solids and gases . An example in liquids is the miscibility of water and ethanol as they mix in all proportions.

Good solvents are likely to be diethyl ether and hexane. (However, PE only dissolves at temperatures well above 100 °C.) (However, PE only dissolves at temperatures well above 100 °C.) Poly(styrene) has a solubility parameter of 9.1 cal 1/2 cm −3/2 , and thus ethyl acetate is likely to be a good solvent.
The upper critical solution temperature (UCST) or upper consolute temperature is the critical temperature above which the components of a mixture are miscible in all proportions. [1] The word upper indicates that the UCST is an upper bound to a temperature range of partial miscibility, or miscibility for certain compositions only.
