Question

2. Describe the effect of temperature on the solubility of (a) solid solute (b) gaseous solute, in water ?​

Answer 1

Answer:

Note 2: The expression is to be used to describe a solid phase containing. more than one substance when, for convenience, one (or more) of the substances, called the solvent, is treated differently from the other substances, called solutes. Note 3: One or several of the components can be macromolecules.

As we indicated above, the only gases that are readily soluble in water are those whose polar character allows them to interact strongly with it.

Explanation:

Answer 2

• Solute state : Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
• Gaseous state : Increasing temperature results in increased kinetic energy. Gas molecules with greater kinetic energy move more rapidly resulting in the intermolecular bonds between the gas solute and solvent breaking. The solubility of gas is affected by changes in pressure on the system. A gas dissolves in liquids to form solutions.
• In Water : For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions
