Q2. What is HPLC and principle
Ans. 
HPLC stands for High Performance Liquid Chromatography. It is a technique used to separate, identify, and quantify components in a mixture.
• HPLC involves a sample being dissolved in a solvent and then pumped through a column packed with a stationary phase.

• The different components in the sample interact differently with the stationary phase, causing them to separate based on their properties.

• The separated components are ...read more

Q1. Defination of pH?
Ans. 
pH is a measure of the acidity or alkalinity of a solution on a scale of 0 to 14.
• pH stands for 'potential of Hydrogen'

• It measures the concentration of hydrogen ions in a solution

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9

Q3. Define molarity, molality, normality.
Ans. 
Molarity is the concentration of a solution in moles of solute per liter of solution. Molality is the concentration of a solution in moles of solute per kilogram of solvent. Normality is the concentration of a solution in equivalent weights of solute per liter of solution.
• Molarity is expressed as moles of solute per liter of solution (M = moles/L).

• Molality is expressed as moles of solute per kilogram of solvent (m = mo...read more

Q5. Principles of Gas chromatography
Ans. 
Gas chromatography is a technique used to separate and analyze compounds in a mixture based on their distribution between a stationary phase and a mobile phase.
• Gas chromatography involves a sample being vaporized and injected into a column with a stationary phase, where it interacts with a carrier gas.

• Compounds in the sample will travel through the column at different rates based on their interactions with the stationa...read more
