A solvent (from the Latin solvo, "loosen, untie, solve") could be a substance that dissolves a solute (a chemically distinct liquid, solid or gas), leading to a solution. A solvent is typically a liquid but may also be a solid, a gas, or an excellent critical fluid.

What is a Polar Solvent?

Polar solvents contain molecules that maintain an electrical charge that has low amperage, which implies the number of electrical current flowing between the molecules is low on the amperage scale. the foremost common example of a polar molecule is water; it contains one oxygen atom and two hydrogen atoms that are set at an angle to the oxygen atom, creating a minor imbalance within the electrical charge (a.k.a. polarity) of the water molecule.

If you place a solid in water, it can dissolve due to the solid’s molecules attracting to the electrical charge of the water molecules. for instance, salt dissolves during this manner when placed in water. the identical thing can happen after you subject a soil to a polar cleaning solvent. However, a polar solvent won't readily dissolve non-polar materials. this can be why polarity is one amongst the chief considerations when choosing a solvent for removing specific forms of accumulations.
