Study Notes
Characteristics of Solutions
- A saturated solution contains the maximum amount of solute dissolved in the solvent, leading to no additional solute being able to dissolve at a given temperature.
- A supersaturated solution has more solute dissolved than what could normally be dissolved by the solvent under standard conditions, often achieved by changing temperature or pressure.
Temperature and Solubility
- The solubility of most solid solutes increases as temperature rises, allowing more solute to dissolve in the solvent.
Concentration Units
- Concentration of a solution is commonly expressed using molarity (M), which specifies the number of moles of solute per liter of solution.
- Other common expressions of concentration include mass percent, volume percent, and molality.
Effects of Dilution
- Dilution reduces the concentration of a solution by adding more solvent without changing the amount of solute, thus increasing the volume while decreasing the ratio of solute to solvent.
Relationship Between Molarity and Volume
- Molarity is inversely related to volume; if the volume of the solution increases (due to dilution), the molarity decreases, assuming the amount of solute remains constant.
Molarity and Its Implications
- Molarity indicates how concentrated a solution is and provides a way to calculate the required amounts of solute and solvent for reactions and dilutions.
- Direct factors affecting molarity include the amount of solute and the total volume of solution.
