Question

After dissolving 5 gms of sugar in 50ml of water, sugar solution is given to you.Can you write any two properties of it?​

Answer 1

Properties of a solution

• A solution is a homogeneous mixture
• The particles of a solution are smaller than 1 nm (10-9 metre) in diameter. So,  they cannot be seen by naked eyes.
• Because of very small particle size, they  do not scatter a beam of light passing  through the solution. So, the path of  light is not visible in a solution.

• The solute particles cannot be  separated from the mixture by the  process of filtration. The solute particles  do not settle down when left undisturbed,  that is, a solution is stable

Mass by mass percentage of a solution

      $=\frac{\text { Mass of solute }}{\text { Mass of solution }} \times 100$

Mass by volume percentage of a solution

          $=\frac{\text { Mass of solute }}{\text { Volume of solution }} \times 100$

Volume by volume percentage of a  solution

           $=\frac{\text { Volume of solute }}{\text { Volume of solution }} \times 100$
