Chapter U4, Problem SV3RE

(a)

Interpretation Introduction

Interpretation:The molecular view diagram of resulting mixture is to be drawn.

Concept introduction:The resulting solution formed by the mixing of two components having different chemical composition is known as mixture.The molecules are not uniformly distributed in water when slightly soluble compound is added to it.

Answer to Problem SV3RE

The molecular view diagram of resulting mixture is

  

Explanation of Solution

When a slightly soluble compound is added to water only few molecules of slightly soluble compound comes in contact with water molecules. The bond between molecules of slightly soluble compound is not completely broken. The molecules form small patches in water.

  

(b)

Interpretation Introduction

Interpretation: The resulting mixture is homogeneous or heterogeneous is to be stated.

Concept introduction:The resulting solution formed by the mixing of two components having different chemical composition is known as mixture. The molecules are not uniformly distributed in water when slightly soluble compound is added to it.

Answer to Problem SV3RE

The resulting mixture of slightly soluble compound with water is heterogeneous mixture.

Explanation of Solution

The resulting solution formed by the mixing of two components having different chemical composition is known as mixture. When the molecules of solute are completely distributed in solvent then the mixture is classified as homogeneous mixture. However, when molecules are not uniformly distributed in solvent it is known as heterogeneous mixture. Therefore, the resulting mixture of slightly soluble compound with water is heterogeneous mixture.
