(A) Identify the solute and solvent in the following solutions :
(i) aerated drinks
(ii) tincture of iodine
(iii) lemon water

(B) State the principle for each of the following methods of separation of mixtures.
(i) centrifugation method
(ii) separation using separating funnel

Solution

(A) (i) Aerated drinks: Solute = Carbon Dioxide, Solvent = Water

(ii) Tincture of iodine: Solute = Iodine, Solvent = Alcohol

(iii) Lemon water: Solute = Sugar, Citric Acid, Solvent = Water

(B) (i) Centrifugation principle: The denser particles are forced at the bottom and lighter particles stay at the top when spun rapidly.

(ii) Separation using separating funnel: Immiscible liquids separate out in layers depending on their densities.
