Question

what is difference between dilution and concentration?

Answer 1

Dilution means add more salute to the solvent where the it becomes a unsaturated solution in normal temperature. When it is heated, The solvent's molecular space will increase and salute gets more space to become super saturated solution. Concentration means equal. Concentrated solution = Saturated solution.

Answer 2

A dilute solution contains a smaller amount of solute than does a concentrated solution . Moreover, a dilute solution contains more solvent than an equal volume of concentrated solution does.
