Question

34. (a) Under which category of mixtures will you classily alloys and why?
(b) A solution is always a liquid. Comment
(c) Can a solution be heterogeneous?​

Answer 1

Explanation:

We classify alloys as Homogenous mixture because the individual particles are not visible but still the mixture exhibit the characteristics of individual Elements.

Consider alloy of Bronze which is made of Cu and Sn. It has properties of copper as well as Tin.

A solution is always a liquid because the solute dissolved is less than the amount of solvent. A solvent cannot dissolve more solute than its saturation level at a particular level. The saturation level is never 100%

Yes the solution can be heterogeneous. Example : Chalk in water

Answer 2

Answer:

Question 34: (a) Under which category of mixtures will you classify alloys and why? Answer: When constituent particles of a combination of two or more element or compound retains their properties, then it is called mixture. In an alloy the constituent particles, hence alloys are classified as mixture.

b)No,Solutions are not always liquid because solution is a mixture of two homogenous substances.It may be liquid ,solid or gaseous. Example: Solution of alcohol in water is a liquid. Air is a solution of different gas. Alloy is a solution which is in the form of solid.

c)NO a solution cannot be a heterogeneous because in a heterogeneous mixture the solute is not dissolved uniformly throughout the mixture.In a True solution solute (liquid/solid/gas) is dissolving uniformly and it can not be a heterogeneous mixture.
