‘Take water in a glaSS and add a teaspoon of sugar in it. Stir the water with a spoon.
The sugar slowly dlssolves in the water. The water with dissolved sugar becomes sweet to taste. Thls sweet water is called a solution of sugar in water.
sugar + Water —> Sugar solution
Similarly, salt dissolves in water to form a solution that tastes salty. Try to dissolve a teaspoonful of sand in water? Does it dissolve? All solids do not
dissolve in water.
,Solvent IS a substance that can dlssolve another substance in it. Water can dissolve many substances. It is therefore called a universal solvent. The substance that
dissolves in a solvent is called a solute.
Solute + Solvent —> Solution
A substance that can dissolve in a solvent is said to be soluble in it, e.g. salt and sugar are soluble in water. A substance that does not dissolve in a solvent
is soluble in it, e.g. sand and sawdust are insoluble in water.
