Match column I with column II.

Matrix:

Column I

Column II
a)
Wheat flour, gram flour, talcum powder
i)
Soluble in water
b)
Salt, sugar, coffee powder, baking powder, detergent
ii)
Insoluble in water

A
a – i, b – ii
B
a – ii; b – i
C
a – i; b – i
D
None of these

Solution:

The substances that dissolve completely in water are termed soluble, while those that do not dissolve in water are termed insoluble. For example, salt, sugar, coffee powder, baking powder and detergent completely mix or dissolve in water; hence, they are soluble in water. On the other hand, wheat flour, gram flour and talcum powder do not dissolve in water. Hence, they are insoluble in water.
