Why do we use normality instead of molarity?

While Molarity refers to the concentration of a compound or ion in a solution, normality refers to the molar concentration only of the acid component or only of the base component of the solution. Thus, normality offers a more in-depth understanding of the solution’s concentration in acid-base reactions.

Why is normality important in chemistry?

Uses of Normality Normality is used in precipitation reactions to measure the number of ions which are likely to precipitate in a specific reaction. It is used in redox reactions to determine the number of electrons that a reducing or an oxidizing agent can donate or accept.

What is the difference between the molarity and normality?

Main Difference – Molarity vs Normality The main difference between molarity and normality is that molarity is the number of moles of a compound present in a mixture of compounds whereas normality is the amount of gram equivalents of a compound present in a mixture of compounds.

Why do chemists use molarity?

Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.

Why is normality used for acids and bases?

While pH is used to record the acidity or alkalinity of natural waters, we use a measurement known as normality to show the concentration of the much stronger acid and base solutions we use in the lab. Normality is a measure of concentration equal to the gram equivalent weight per liter of solution.

What is the difference between normality and molarity and molality?

Molarity ( ) is defined as the number of moles of solute per liter of solution. Molality ( ) is defined as the number of moles of solute per kilogram of solvent. Normality ( ) is defined as the number of equivalents per liter of solution.

Why do we need normality factor?

Normality factor and titration error are important in analytical chemistry for the determination of the variation of the observed result from the theoretically true result for the same experiment.

What is normality used for?

In acid-base chemistry, normality is used to express the concentration of hydronium ions (H3O+) or hydroxide ions (OH−) in a solution. Here, 1feq is an integer value. Each solute can produce one or more equivalents of reactive species when dissolved.

What is the advantage of using molarity concentration in chemistry lab?

The first advantage is that it’s easy and convenient to use because the solute may be measured in grams, converted into moles, and mixed with a volume. The second advantage is that the sum of the molar concentrations is the total molar concentration. This permits calculations of density and ionic strength.

Which one is better molarity or normality?

Normality is NOT NECESSARILY better than Molarity. It us just more useful in certain cases, those certain cases being when we talk about acids/bases/salts/pH/ionic calculations. Molarity and Normality arise from the same fundamental principle – finding the molar strength of a solute per unit volume of solution.
