What is Solution, Solute and Solvent?

In short

A solution is a uniform mixture of a solute dissolved in a solvent. The solvent is the substance present in the larger amount, usually the liquid.

In simple words

In salt water, salt is the solute and water is the solvent. A solution is clear, its particles are too small to scatter light, and the solute does not settle. The concentration of a solution can be given as grams per litre, as a percentage, or as molarity, M=moles of solutelitres of solutionM = \dfrac{\text{moles of solute}}{\text{litres of solution}}M=litres of solutionmoles of solute​. A solution that cannot dissolve any more solute at a given temperature is saturated.

Example
