A solution forms when a solute dissolves in a solvent. For salty water, salt is the solute and water is the solvent.
Water is a very common solvent. Solubility is how much solute can dissolve; warming water usually lets more solid solute dissolve. Clean, safe water is essential for life.
Remember
- Solution = solute + solvent.
- Water is the "universal solvent"; heating often increases solubility.
