Study Notes
Normality
- A gram equivalent weight of solute per liter of solution is the normality unit of concentration for a chemical solution.
- Normality is the only measure of chemical concentration that is dependent on the chemical reaction under investigation.
- N, eq/L, and meq/L are standard units of normality.
- Normality is not always the most frequent measure of concentration, and its application to all chemical solutions is not acceptable.
- Molarity or molality are superior possibilities for units in most other circumstances.
Formula and Calculation
- N = Molarity × Molar mass × [Equivalent mass]-1
- To indicate concentration, a specific equivalency factor must be employed.
Applications of Normality
- Normality might be useful in acid-base chemistry.
- Normality might be useful in redox processes.
- Normality might be useful in precipitation reactions.
Learn about normality, its units, and its significance in measuring chemical concentration. Understand the concept of gram equivalent weight and its relation to normality.
