Metrochem Api Chemist Interview Questions, Process, and Tips

pH is a measure of acidity or alkalinity of a solution on a scale of 0 to 14.

• pH stands for 'potential of Hydrogen'

• pH scale ranges from 0 (most acidic) to 14 (most alkaline)

• Neutral pH is 7, like pure water

• Acids have pH below 7, bases have pH above 7

• pH is important in various industries like agriculture, food, and medicine

Organic chemistry is the study of carbon-based compounds. pH measures acidity or alkalinity. TLC is a technique for separating compounds.

• Organic chemistry focuses on the study of carbon-containing compounds.

• pH is a measure of the acidity or alkalinity of a solution.

• TLC (Thin Layer Chromatography) is a technique used to separate and analyze compounds in a mixture.

• Polar solvents dissolve polar compounds, while non-polar ...read more

AA is a common abbreviation for amino acids. They have a general structure of NH2-CHR-COOH and can undergo various named reactions like Grignard reaction.

• AA stands for amino acids which are the building blocks of proteins

• Their general structure is NH2-CHR-COOH where R can be any of the 20 different side chains

• Grignard reaction is a named reaction used to form carbon-carbon bonds and is commonly used in organic synthesi

Density of solvents is an important property for various chemical processes.

• Density is the mass per unit volume of a substance.

• Solvents with higher density can dissolve more solutes.

• Density can be affected by temperature and pressure.

• Examples of solvents with different densities include water (1 g/mL), ethanol (0.789 g/mL), and chloroform (1.48 g/mL).
