Question

which of the following is a true solution? (1)milk (2) chalk powder in water (3) salt solution (4) blood

Answer 1

Good morning
! Salt is true solution!

Answer 2

The salt solution is a true solution.

• A true solution has a specific solute and solvent.
• Milk is a homogeneous mixture of fat, water, lipid etc so, it doesn't have a specific solute. Thus it is not a true solution.
• Chalk does not dissolve in water so, it is not a true solution.
• Salt completely dissolves in water and forms a true solution.
• Blood is a homogeneous mixture of enzymes, water etc so, it doesn't have a specific solute. Thus it is not a true solution.
• Hence the correct option is 3.
