What is normality in chemistry with example?
The normality of a solution is the gram equivalent weight of a solute per liter of solution. For example, the concentration of a hydrochloric acid solution might be expressed as 0.1 N HCl. A gram equivalent weight or equivalent is a measure of the reactive capacity of a given chemical species (ion, molecule, etc.).
What is normality and molarity?
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.
What is normality simple words?
Normality is a measure of concentration equal to the gram equivalent weight per liter of solution. The solute’s role in the reaction determines the solution’s normality. Normality is also known as the equivalent concentration of a solution.
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.
How do you calculate the normality of a liquid?
How do I calculate my normality? You can use the formula N= weight of substance in grams*1000/ equivalent weight of substance*volume required in mL.
What is a PPM in chemistry?
This is an abbreviation for “parts per million” and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. One ppm is equivalent to the absolute fractional amount multiplied by one million.
Why is normality important in chemistry?
In acid-base chemistry, normality is used to express the concentration of hydronium ions (H3O+) or hydroxide ions (OH−) in a solution. In precipitation reactions, the equivalence factor measures the number of ions which will precipitate in a given reaction.
