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...
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.

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
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
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...
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...
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.

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)
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.
I applied via Company Website and was interviewed in May 2024. There were 2 interview rounds.
