Q2. Principle of HPLC and working principle?
Ans. 
HPLC is a chromatographic technique used to separate, identify, and quantify components in a mixture based on their interactions with a stationary phase and a mobile phase.
• HPLC stands for High Performance Liquid Chromatography.

• It involves passing a liquid sample through a column packed with a stationary phase, where different components interact differently and are separated based on their affinity for the stationary p...read more

Q1. What's principal of HPLC
Ans. 
HPLC stands for High Performance Liquid Chromatography, a technique used to separate, identify, and quantify components in a mixture.
• HPLC involves a stationary phase, a mobile phase, and a detector.

• The sample is injected into the system and carried by the mobile phase through the stationary phase.

• Different components in the sample interact differently with the stationary phase, leading to separation.

• The detector measur...read more

Q2. What's Dissolution stages
Ans. 
Dissolution stages refer to the different phases in which a solid substance dissolves in a liquid medium.
• Dissolution begins with the solid substance breaking down into smaller particles

• The smaller particles then disperse in the liquid medium

• Finally, the particles fully dissolve and become uniformly distributed in the liquid

Q5. What's Normality, Molarity and Molality?
Ans. 
Normality, Molarity, and Molality are different units of concentration used in chemistry.
• Normality is the number of equivalents of a substance dissolved in a liter of solution.

• Molarity is the number of moles of solute per liter of solution.

• Molality is the number of moles of solute per kilogram of solvent.

• Normality is used in acid-base reactions, while Molarity and Molality are more commonly used in general chemistry.

• Ex...read more
