Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

- [ ] Ethanol
- [ ] Hexanes
- [ ] Water

#### Detailed Explanation of the Solubility Data Table

The table provided lists the solubility of compound A in various solvents at two different conditions: when the solvent is boiling and when it is cold.

- **Hexanes**: Solubility is 0.3 grams per 100 mL in boiling hexanes and 0.02 grams per 100 mL in cold hexanes.
- **Ethanol**: Solubility is 10 grams per 100 mL in boiling ethanol and 9 grams per 100 mL in cold ethanol.
- **Water**: Solubility is 4 grams per 100 mL in boiling water and 0.2 grams per 100 mL in cold water.
- **Methanol**: Solubility is 3 grams per 100 mL in boiling methanol and 0.3 grams per 100 mL in cold methanol.

By comparing the solubility of compound A in different solvents under boiling and cold conditions, you can determine which solvent is most effective for purification by crystallization. Effective purification often relies on a significant difference in solubility between hot and cold solvents to allow for maximum recovery of the compound when cooled.

Note: The best solvent for crystallization usually has a high solubility for the compound when hot and a significantly lower solubility when cold.
