In which types of reactions is normality a useful measure of concentration?
Acid-base chemistry, redox processes, and precipitation reactions
Why is normality not always a frequent measure of concentration?
Its application to all chemical solutions is not acceptable
What is a more superior possibility for units in most circumstances?
Molarity or molality
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.
