Chromatography is a technique used to separate and analyze mixtures of substances based on their different properties.

• Chromatography involves a stationary phase and a mobile phase.

• The stationary phase can be a solid or a liquid that is fixed in place.

• The mobile phase is a liquid or gas that carries the mixture through the stationary phase.

• Different components of the mixture interact differently with the stationary phas...read more

Normality refers to the concentration of a substance in a solution, expressed as the number of equivalents per liter.

• Normality is a measure of the concentration of a substance in a solution.

• It is expressed as the number of equivalents per liter (eq/L).

• Normality is commonly used in acid-base reactions and redox reactions.

• For example, a 1M solution of hydrochloric acid (HCl) is also 1N because HCl is monoprotic.

• However, ...read more

Molality is a measure of the concentration of a solute in a solvent, expressed as the number of moles of solute per kilogram of solvent.

• Molality is different from molarity, which is the number of moles of solute per liter of solution.

• It is commonly used in chemistry and pharmacy to accurately measure the concentration of a solute in a solvent.

• Molality is temperature-independent, unlike molarity.

• For example, a solution ...read more
