What is a solution? 🧪
- Definition: A solution is a homogenous mixture of two or more components.
- Solvent: The major component. Think of this like the water in lemonade!
- Solute: The other ingredients, like sugar in lemonade.
- Examples: Sugar in water (water is solvent, sugar is solute). Even in a 96% ethanol in water solution, water is still considered the solvent.
Classifying solutions by concentration 📊
- Concentrated: Think of this as a super sweet lemonade, with lots of sugar.
- More than 10g of solute per 100g of solvent.
- Dilute: Like weak tea, with a small proportion of solute.
- Less than 10g of solute per 100g of solvent.
Molar concentration (molarity) 🧐
- Molar Concentration: The ratio of solute amount to solution volume.
- Units: moldm(-3), also known as molL(-1), or M.
- Examples:
- 1mmol dm(-3) = 1×10(-3) mol dm(-3)
- 1µmol dm(-3) = 1×10(-6) mol dm(-3)
- Saying "2.5M NaOH" means each liter contains 2.5 moles of NaOH.
Mass concentration 🏋️
- Mass Concentration: The ratio of the mass of the solute to the volume of the solution.
- Common Units: gdm(-3) and gcm(-3).
- Relation to Molar Concentration: Depends on the molar mass.
