Brief explanations:
- Increasing temperature decreases the solubility of gases. — True. Gas solubility in liquids typically falls as temperature rises (Henry's law behavior and exothermic dissolution).
- Stirring increases the solubility of solids. — False. Stirring speeds up the rate of dissolution but does not change the equilibrium solubility.
- Increasing pressure increases the solubility of liquids. — False. Pressure has negligible effect on solubility of liquid solutes; pressure mainly affects gases.
- Decreasing temperature decreases the solubility of solids. — True (for most solids). Most solid solutes are more soluble at higher temperatures, so lowering T usually lowers their solubility (there are exceptions).
- Increasing pressure increases the solubility of gases. — True. Gas solubility in a liquid is proportional to its partial pressure above the liquid (Henry’s law).
- Decreasing the amount of solvent decreases the solubility of solids, liquids, and gases. — False. Solubility is an intensive property (concentration at equilibrium); changing the total amount of solvent doesn’t change the solubility, though it changes how much solute can actually dissolve before saturation.
