Question

which of the following solution has diameter of its constituent particles larger than 1 NM
1 Tincture of iodine
2 Aqueous solution
3 soda water
4 wheat flour in water

Answer 1

Coarse solution: When the solution has diameter of its constituent particles larger than 1 NM, the solution is called as a coarse solution.

Aqueous solution: A solution where water acts as the solvent is referred to as an aqueous solution.

In aqueous solution of sugar,

• Sugar is dissolved
• Forms a homogeneous mixture
• Forms a coarse solution

Hence, the size of the particles are larger than 1 NM

The answer is (2) Aqueous solution of sugar
