Concentration in Solutions
Learning Time: 4-12 hours
Content: Concentration in solutions is a quantitative topic that expresses the amount of solute and solvent. This area covers molarity, molality, mass percent, volume percent, ppm (parts per million), dilution, and concentration changes. The TYT focuses on basic concentration units, while the AYT focuses on titration and mixture analysis. The current 2025 curriculum also covers concentration measurement techniques in environmental chemistry. Learning this topic provides a fundamental tool for controlling chemical reactions.
- Concentration Units:
- Molarity (M = n/V)
- Molality (m = mol/kg)
- Mass Percent (% m/m)
- Additional Concentration Types:
- Volume Percent (% v/v)
- ppm and ppb (Environmental Measurements)
- Normality (Equivalent Weight)
- Dilution and Concentration:
- Dilution Formula (M₁V₁ = M₂V₂)
- Concentration Change
- Solution Preparation Techniques
- Applications:
- Titration Analyses
