Q1. 1. Brief about HPLC analysis
Ans. 
HPLC analysis is a 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 is commonly used in pharmaceutical, environmental, and food industries

• HPLC analysis involves injecting a sample into a column packed with a stationary phase, then eluting it with a mobile phase

• The com...read more

Q1. Molarity of Hcl
Ans. 
Molarity of HCl is a measure of concentration of hydrochloric acid in a solution.
• Molarity is defined as the number of moles of solute per liter of solution.

• To calculate molarity, divide the number of moles of solute by the volume of the solution in liters.

• For example, if you have 0.5 moles of HCl in 1 liter of solution, the molarity would be 0.5 M.

Q1. What is polarity and how it effect the molecules
Ans. 
Polarity refers to the separation of electric charge within a molecule, which affects its chemical properties.
• Polarity is determined by the difference in electronegativity between atoms in a molecule.

• Polar molecules have a positive and negative end, while nonpolar molecules have an even distribution of charge.

• Polarity influences various properties of molecules, such as solubility, boiling point, and intermolecular forc...read more

Q2. Types of chromatography
Ans. 
Chromatography is a technique used to separate and analyze mixtures of substances based on their different interactions with a stationary phase and a mobile phase.
• Gas chromatography (GC) separates volatile compounds based on their vapor pressure and affinity for the stationary phase.

• Liquid chromatography (LC) separates compounds based on their polarity and affinity for the stationary phase.

• Ion exchange chromatography s...read more

Q3. Chiral compound and its characteristics
Ans. 
Chiral compounds are molecules that have a non-superimposable mirror image.
• Chiral compounds have an asymmetric carbon atom, also known as a chiral center.

• They exist in two enantiomeric forms, which are mirror images of each other.

• Chiral compounds exhibit optical activity, meaning they rotate the plane of polarized light.

• They have different physical and chemical properties from their mirror images.

• Examples of chiral com...read more
