Study Notes
Solutions Overview
- A binary solution consists of two components: a solute and a solvent.
- The solute in a binary solution is the component present in a smaller quantity.
- A saturated solution contains the maximum amount of solute that can be dissolved at a specific temperature; beyond this, the solution cannot hold more solute.
- An unsaturated solution can dissolve additional solute without changing the temperature.
- Supersaturated solutions contain less solute than necessary to reach saturation at a given temperature.
Solubility Details
- The maximum amount of solute that can dissolve in a given quantity of solvent is known as its solubility.
- Factors affecting solubility include temperature, pressure, and the nature of the solute and solvent.
Henry's Law
- According to Henry's Law, the partial pressure of a gas in vapor phase is inversely proportional to its mole fraction in a solution.
- An increase in temperature leads to an increase in the value of KH, resulting in lower solubility for gases in liquids.
Concentration Measurements
- Percentage by weight (w/w%) is used to express the amount of solute present in 100 g of solution.
- Molarity (M) represents the concentration of a solution based on the amount of solute per liter of solution.
Additional Information
- Concentrated solutions typically have a lower relative amount of solute compared to the solvent.
- To alleviate decompression sickness in divers, controlled exposure to pressures and gradual decompression is used.
- At high altitudes, reduced pressure leads to lower O2 concentrations in climbers' blood.
- In soft drinks, CO2 is added at high pressure to enhance its solubility.
