Question

C. State whether the following statements are TRUE or FALSE,
1. Solubility of solids decreases on increasing the temperature.
2. Fractional distillation can be used for separating a mixture of miscible liquids,
3. Water is called a universal solvent because most of the substances are soluble in​

Answer 1

Answer:

1.FALSE

2.TRUE

3.TRUE

Answer 2

Answer:

1.FALSE

2.TRUE

3.TRUE

Explanation:

1. Because of increase in temperature there is increase in kinetic energy and increase in kinetic energy allows solvent molecules to break solute molecules that are held together by intermolecular forces hence their solubility increases
