A solvent dissolves a solute, resulting in a solution Ethyl acetate, a nail polish solvent. [1] A solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
As a solid, sodium methoxide is polymeric, with sheet-like arrays of Na + centers, each bonded to four oxygen centers. [3] The structure, and hence the basicity, of sodium methoxide in solution depends on the solvent. It is a significantly stronger base in DMSO where it is more fully ionized and free of hydrogen bonding. [4]
Furthermore, it promotes the hydrolysis of some carbonyl sulfide, a common component of sour gas: COS + H 2 O → CO 2 + H 2 S. This hydrolysis step further enriches the hydrogen sulfide content of the off-gas when the NMP is stripped. The sulfur-rich gas is well suited for a Claus unit, which affords solid elemental sulfur.

Gas: Gas Gas mixture: air (oxygen and other gases in nitrogen) not possible: Liquid: Aerosol: fog, mist, vapor, hair sprays, moisted air Aerosol: rain (also produces rainbows by refraction on water droplets) Solid: Solid aerosol: smoke, cloud, air particulates: Solid aerosol: dust, sand storm, ice fog, pyroclastic flow: Gas Liquid Oxygen in water
This arises from the fact that polar solvents stabilize the formation of the carbocation intermediate to a greater extent than the non-polar-solvent conditions. This is apparent in the ΔE a, ΔΔG ‡ activation. On the right is an S N 2 reaction coordinate diagram. Note the decreased ΔG ‡ activation for the non-polar-solvent reaction ...
Lipophilicity (from Greek λίπος "fat" and φίλος "friendly") is the ability of a chemical compound to dissolve in fats, oils, lipids, and non-polar solvents such as hexane or toluene. Such compounds are called lipophilic (translated as "fat-loving" or "fat-liking" [1] [2]). Such non-polar solvents are themselves lipophilic, and the ...
Heptane and its many isomers are widely used in laboratories as a non-polar solvent. [11] As a liquid, it is ideal for transport and storage.In the grease spot test, heptane is used to dissolve an oil spot to show the previous presence of organic compounds on a stained paper.
Polar solvents can be used to dissolve inorganic or ionic compounds such as salts. The conductivity of a solution depends on the solvation of its ions. Nonpolar solvents cannot solvate ions, and ions will be found as ion pairs. Hydrogen bonding among solvent and solute molecules depends on the ability of each to accept H-bonds, donate H-bonds ...
