Consider the following mixtures: steel, air, muddy water, oil & vinegar a) Propose a method to separate the components of the above mixtures b) Identify the property that allows the separation of the above mixtures

Answer:

(a) 

 (i)STEEL is an alloy and hence its components are separated with the process of Liquation. It is melted with the help of certain acids. After that metals and non metals from the Steel are extracted with the help of liquid extraction

(ii) Air is separated into its components with the help of distillation in air separation plant. Cryogenic rectification is used in the air fractionating columns of air separating plant.

different gases present in the air gets separated with the help of fractional distillation

(iii)muddy water is separated with the help of decantation in which mud gets separated from the water.

(iv)Fractional distillation is used because vinegar and water are almost miscible in nature.

(b) (i) Melting Property

(ii) Different vapor pressures and boiling points

(iii) Immiscible property or heterogenous mixture.

(iv) different vapor pressure.
