Q2. 1) What is chromatography? 2) What is spectroscopy? 3) What is molarity?
Ans. 
Chromatography is a technique used to separate and analyze mixtures. Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Molarity is a measure of the concentration of a solution.
• Chromatography involves passing a mixture through a stationary phase and a mobile phase to separate its components.

• Spectroscopy can be used to identify the chemical composition of a substance by analyzing ...read more

Q1. What is molarity ?
Ans. 
Molarity is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution.
• Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.

• It is commonly denoted by the symbol 'M'.

• For example, a 1M solution of sodium chloride contains 1 mole of sodium chloride dissolved in 1 liter of water.

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

Q8. What's OOS and OOT?
Ans. 
OOS stands for Out of Specification and OOT stands for Out of Trend.
• OOS refers to a result that falls outside the acceptance criteria specified in the test procedure.

• OOT refers to a result that shows a trend outside the expected range over time.

• Both OOS and OOT results may indicate potential issues with the quality or consistency of the product being tested.

Q1. Defination of Normality?
Ans. 
Normality refers to the state of being within the typical or expected range of behavior or characteristics.
• Normality is often used in statistics to describe data that follows a bell-shaped curve, with the majority of values clustered around the mean.

• In chemistry, normality is a measure of concentration, specifically the number of equivalents of a substance per liter of solution.

• In psychology, normality can refer to beh...read more

Q2. The number of grams equivalent to solute that is dissolved in the one litre solution
Ans. 
The number of grams of solute dissolved in one liter of solution is known as the concentration of the solution.
• Concentration is typically expressed in units such as grams per liter (g/L) or molarity (mol/L).

• To calculate concentration, divide the mass of the solute by the volume of the solution.

• For example, if 10 grams of salt are dissolved in 1 liter of water, the concentration of the solution is 10 g/L.
