- Q1. How to identify the samples for analysis
- Ans.
Samples can be identified based on labeling, appearance, unique characteristics, and accompanying documentation.
Check the labeling on the sample containers for identification information such as sample name, ID number, and date collected.
Examine the physical appearance of the samples, noting color, texture, and any visible impurities.
Look for unique characteristics such as odor or solubility that can help differentiate...
- Q2. What is nmr spectroscopy
- Ans.
NMR spectroscopy is a technique used to study the structure and composition of molecules by analyzing the magnetic properties of atomic nuclei.
NMR spectroscopy involves applying a magnetic field to a sample, which causes the nuclei of certain atoms to resonate at specific frequencies.
The resulting signals are detected and used to create a spectrum that provides information about the chemical environment of the nuclei.

- Q3. What is the ph and its definition
- Ans.
pH is a measure of 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
- Q4. How to identify the ranges in nmr and uv
- Ans.
Ranges in NMR and UV can be identified by analyzing the chemical shifts and absorption peaks, respectively.
In NMR, chemical shifts are measured in parts per million (ppm) and can range from 0 to 12 ppm for proton NMR.
In UV spectroscopy, absorption peaks are observed at specific wavelengths, typically ranging from 200 to 400 nm.
Interpreting the peaks and shifts in the spectra can help determine the functional groups pre
- Q5. Why silica gel is used as stationary phse
- Ans.
Silica gel is used as a stationary phase in chromatography due to its high surface area and ability to interact with a wide range of compounds.
Silica gel has a high surface area, allowing for better separation of compounds based on their interactions with the stationary phase.
It can interact with a wide range of compounds, making it versatile for different types of chromatography techniques.
Silica gel is chemically ine...
- Q6. What is oxidation and reduction
- Ans.
Oxidation is the loss of electrons by a molecule, atom, or ion, while reduction is the gain of electrons.
Oxidation involves the addition of oxygen or loss of hydrogen, while reduction involves the loss of oxygen or gain of hydrogen.
Oxidation increases the oxidation state of a molecule, while reduction decreases it.
An example of oxidation is the rusting of iron, where iron reacts with oxygen to form iron oxide.
An exampl...
- Q7. What is isomerism
- Ans.
Isomerism is a phenomenon in which two or more compounds have the same molecular formula but different structural arrangements.
Isomers have different physical and chemical properties.
Types of isomerism include structural isomerism, stereoisomerism, and conformational isomerism.
Example: Structural isomers - butane and isobutane.
Example: Stereoisomers - cis and trans isomers of 2-butene.
- Q8. The same molecular formula but different structure are Present inthe spease

- Q1. Principal ofHPLC
- Ans.
HPLC 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 involves pumping a sample mixture through a column packed with a stationary phase, where different components interact differently and are separated based on their affinity for the stationary phase.
The separated components are detected as they exit the column a...
- Q2. Formula of acid
- Ans.
The formula for an acid is typically written as HX, where X represents an anion.
Acids are substances that donate protons (H+ ions) in a chemical reaction
The general formula for an acid is HX, where H represents a hydrogen ion and X represents an anion
Examples include HCl (hydrochloric acid), H2SO4 (sulfuric acid), and HNO3 (nitric acid)

- Q1. What is pressure unit?
- Ans.
Pressure unit is a measurement of force per unit area, commonly used units include pascal, bar, and psi.
Pressure unit is a measurement of force per unit area
Commonly used units include pascal (Pa), bar, and psi (pounds per square inch)
Pressure can also be measured in atmospheres (atm) or millimeters of mercury (mmHg)
- Q2. What is nitration?
- Ans.
Nitration is a chemical reaction in which a nitro group is added to a molecule.
Nitration involves the substitution of a nitro group (NO2) for another functional group in a molecule.
Commonly used nitrating agents include nitric acid (HNO3) and sulfuric acid (H2SO4).
Nitration is often used in the synthesis of explosives like TNT (trinitrotoluene) and nitroglycerin.

- Q1. What is acidity?
- Ans.
Acidity is the measure of the concentration of hydrogen ions in a solution.
Acidity is measured on the pH scale, which ranges from 0 to 14.
A pH of 7 is neutral, while a pH below 7 is acidic and above 7 is basic.
Acidity can affect the properties and behavior of substances, such as their solubility and reactivity.
Examples of acidic substances include vinegar, lemon juice, and battery acid.
- Q2. Where are using indicators?
- Ans.
Indicators are used in quality control to determine the endpoint of a reaction or to indicate the presence of a specific substance.
Indicators are used in titrations to determine the endpoint of a reaction.
They can also be used to indicate the presence of a specific substance in a sample.
Common indicators include litmus paper, phenolphthalein, and methyl orange.
Indicators can be organic compounds or inorganic compounds.

- Q3. Indicators types?
- Q4. What is titration & using these solution?
- Ans.
Titration is a technique used to determine the concentration of a solution by reacting it with a solution of known concentration.
Titration involves adding a solution of known concentration (the titrant) to a solution of unknown concentration until a reaction is complete.
The point at which the reaction is complete is called the endpoint.
The endpoint is usually detected using an indicator, which changes color when the re...
