Adboxers Interview Questions and Answers

A detector is used in gas chromatography to measure the concentration of analytes in the sample.

• The detector is an essential component of a gas chromatography system.

• It detects and quantifies the separated components of a sample.

• Different types of detectors are used, such as flame ionization detector (FID), thermal conductivity detector (TCD), and electron capture detector (ECD).

• The choice of detector depends on the specific analytes being measured.

• Detectors provide a signal ...read more

Boling point tungsten does not exist as tungsten has a very high melting point.

• Tungsten has a melting point of 3422°C, which is the highest of all metals.

• The boiling point of tungsten is not applicable as it does not exist in a liquid state under normal conditions.

• Tungsten is commonly used in high-temperature applications such as light bulb filaments and rocket nozzles.

The pH range in drinking water typically falls between 6.5 and 8.5.

• The pH range in drinking water is important for maintaining water quality and safety.

• A pH below 6.5 may indicate acidic water, while a pH above 8.5 may indicate alkaline water.

• The ideal pH range for drinking water is generally considered to be between 6.5 and 8.5.

• pH levels outside this range may affect the taste, odor, and safety of the water.

• For example, acidic water with a low pH may corrode pipes, while alk...read more

Bases are used in laboratories for various purposes, including pH adjustment, neutralization reactions, and synthesis of chemicals.

• Bases are substances that can accept protons or donate pairs of electrons.

• They are commonly used to adjust the pH of solutions by neutralizing acidic substances.

• Bases are also used in neutralization reactions to convert acids into salts and water.

• In chemical synthesis, bases are often employed as catalysts or reactants.

• Examples of bases commonly u...read more

Organic chemistry is the branch of chemistry that deals with the study of carbon-based compounds and their properties.

• Organic chemistry focuses on the structure, properties, composition, reactions, and synthesis of carbon-based compounds.

• It involves the study of hydrocarbons, such as alkanes, alkenes, and alkynes, as well as functional groups like alcohols, ethers, and carboxylic acids.

• Organic chemistry plays a crucial role in pharmaceuticals, polymers, dyes, flavors, fragran...read more
