Which of the following statements is NOT correct regarding mixtures?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Colloids are heterogeneous mixtures in which the particle size is large.
-
Colloids are indeed heterogeneous mixtures, but the particle size is not very large.
-
The particle size in colloids ranges between 1 to 1000 nanometers, which is neither as small as molecules nor as large as visible particles.
-
Hence, the statement that colloids have large particle size is incorrect.
-
In a solution, the major component is called the solvent, and the minor component is called the solute.
-
A solution is a homogeneous mixture where two or more substances are completely mixed.
Explanation of other options
-
Option 2 is correct because the major component in a solution is the solvent.
-
Option 3 is correct since the minor component is the solute.
-
Option 4 is correct as a solution is a homogeneous mixture.
-
Therefore, only Option 1 is incorrect.
