Study Notes
Definitions and Key Concepts
- A solute is a substance that dissolves another substance to form a solution.
- Molarity (M) is defined as the number of moles of solute per liter of solution.
- The maximum amount of solute that can be dissolved in a solution is called saturation.
- A 1 Molar (M) solution is characterized by containing 1 mole of solute in 1 liter of solution.
Concentration Measurements
- Concentration can be expressed as moles of solute per liter of solution, known as molarity.
- The major component in a solution is referred to as the solvent.
- Mass percent indicates the number of grams of solute in 100 grams of the solution.
- Volume percent is defined as the number of milliliters of solute in 100 milliliters of the solution.
- Normality (N) measures the number of equivalents of solute per liter of solution.
Calculations and Conversions
- To find the weight of NaCl for a 0.5 M solution, use the molarity formula: M = mass / molar mass.
- The concentration of 10% NaOH can be converted to molarity using its density and percentage.
- Mass percent is calculated by dividing the weight of solute by the weight of solution and multiplying by 100%.
Chemical Equivalence
- In acid-base chemistry, an equivalent refers to the mass of chemical capable of donating or accepting one mole of protons.
- In redox chemistry, an equivalent measures the mass of a substance that donates or accepts one mole of electrons.
Measurement Apparatus
- An appropriate apparatus for measuring the amount of NaCl often includes a balance for weighing and volumetric flasks for solution preparation.
Additional Notes
- To prepare a 0.3 M solution from 10% NaOH (% w/w), the density of NaOH (1.1111 g/mL) is essential for calculations.
