Question

Define the following terms

a. crystallization
b. radical
c. mixture​

Answer 1

(a) Crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.

(b) A radical is an atom of an element or a group of atoms of different elements that behaves as a single unit with a positive or negative charge on it.

(c) Mixtures are constituted by more than 1 kind of pure form known as substance. There are 2 types of mixture:-

(i) homogeneous

A mixture in which the constituents are uniformly distributed throughout without any clear boundary of separation

(ii) Heterogeneous

A mixture in which constituents don't have uniform composition and has a visible boundary of separation.

Answer 2

a) Crystallization :- Crystallization is a chemical process in which the solid-liquid separation technique occurs. This process causes mass transfer of a solute from the liquid solution to a pure solid crystalline phase.

b) Radical :- A radical is an atom of an element or a group of atoms of different elements that behaves as a single unit with a positive or negative charge on it.

c) Mixture :- A mixture is a combination of two or more substances (elements or compounds) which is not done chemically.
