Solvent:

  • Solvent is a substance which dissolves the solute in the solution.
  • It is used to dissolve the solute.
  • Water is used to dissolve much number of substances so water is known as the universal solvent.

Solvent

Solute + Solvent = Solution

For example, The sugar solution can be made by dissolving sugar crystals in water. Here, Sugar crystals are solute, water is the solvent used.

Classification:

The solvent can be classified as

  • Polar solvent
  • Non Polar solvent

“Like dissolves Like”

  1. Polar solvent:

The substance which dissolves in polar solvent is known as polar molecules.

For Example, Water.

2. Non Polar solvent:

The substance which do not dissolve in water is known as non polar molecules.

Health hazards of solvents:

  • The short term exposure to solvents may cause irritation in eye, lungs and skin, headache, dizziness.
  • Organic solvents are carcinogenic, reproductive hazards and neurotoxins.
  • The long term exposure to solvents may cause liver, brain and kidney damage.
