Normality – FAQs
Question 1: What is the difference between Molarity and Normality?
Answer:
The number of moles of solute per liter of solution is known as morality, whereas the number of grams equivalent of solute per liter of solution is known as normality.
In addition, whereas Molarity is a measurement of the moles in respect to the total volume of the solution, Normality is a measurement of the gram equivalent in relation to the total volume of the solution.
Question 2: What is Gram equivalent?
Answer:
The gram equivalent is defined by the amount or the mass of the substances that is utilized to displaces a fixed amount of another substance.
Question 3: What is the formula for Molarity?
Answer:
The formula to calculate the molarity, M is
Molarity, M = Number of moles of Solute / Volume of Solution in Liters.
Question 4: What is the relation between normality and molarity?
Answer:
The relation between molarity and normality is given by,
Normality (N) = Molarity × Molar mass / Equivalent mass
Question 5: Write any two uses of Normality.
Answer:
Uses of Normality,
- In precipitation reactions, normality is used to determine how many ions are expected to precipitate.
- It determines how many electrons a reducing or oxidizing substance can contribute or absorb in redox processes.
Normality – Definition, Formula, Equations and Solved Examples
The normality formula is used to measure the concentration of a solution like molarity and molality. Normality is a measure of the number of grams equivalent to solute present given volume of the solution. Redox reactions, precipitation reactions, and acid-base chemical reactions all often make use of normality. It depends on the temperature and the chemical reaction being observed.
The term “equivalent concentration” describes how reactive a solution is. This is frequently used in redox reactions and acid-base reactions. In physical chemistry, one of the important terms used is the normality formula.
