Effect of temperature and pressure

Outline the effect of:
  •     temperature
  •     pressure
on the solubility of gases and salts

  • For gases:
    • Solubility increases as gas pressure increases.
    • Solubility decreases as temperature increases.
  • For salts:
    • Solubility is largely unaffected by pressure.
    • Solubility increases as temperature increases.
