pH is a measure of the 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 values below 7, bases have pH values above 7
pH is important in various industries like water treatment, food processing, and pharmaceuticals
A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, while a non-catalyst does not participate in the reaction.
Catalysts lower the activation energy required for a reaction to occur
Non-catalysts do not alter the activation energy of a reaction
Examples of catalysts include enzymes, transition metals, and acids
Examples of non-catalysts include solvents and inert

pH is a measure of the acidity or alkalinity of a solution.
pH stands for 'potential of hydrogen'.
It is a logarithmic scale ranging from 0 to 14.
A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.
pH is determined by the concentration of hydrogen ions in a solution.
Examples: Lemon juice has a pH of around 2, while baking soda has a pH of around 9.
PH represents the concentration of hydrogen ions in a sample.
PH is measured on a scale of 0-14, with 7 being neutral.
A lower PH indicates higher acidity, while a higher PH indicates higher alkalinity.
PH can be measured using a PH meter or through chemical indicators.
The PH of a sample can affect its chemical properties and reactions.
LOD stands for Limit of Detection. It is the lowest concentration of a substance that can be reliably detected.
LOD is used to determine the sensitivity of an analytical method.
It is usually expressed as a concentration or mass.
Water is a chemical compound composed of hydrogen and oxygen, while LOD is a term used in analytical chemistry.
LOD is important in environmental testing to determine the presence of contaminants ...

I applied via Referral and was interviewed before Sep 2020. There was 1 interview round.
The interview question covers topics such as Lewis acid, pH, acid and base, organic chemistry, periodic table, chemical formulas, and pH measurement without a pH meter.
Lewis acid is an electron acceptor, examples include AlCl3 and FeCl3
pH is a measure of acidity or basicity, with a range of 0-14
Acids donate H+ ions, bases accept H+ ions
Organic chemistry deals with carbon-based compounds, examples include ethanol and gl...
Benzene is a colorless, highly flammable liquid with a sweet odor. It is a basic building block of many chemicals.
Benzene is a hydrocarbon with the chemical formula C6H6.
It is a natural constituent of crude oil and gasoline.
Benzene is used in the production of plastics, synthetic fibers, rubber, dyes, detergents, and pharmaceuticals.
Exposure to benzene can cause cancer and other health problems.
Benzene is also a major ...
Water has a boiling point of 100°C and a melting point of 0°C. Other solvents have varying boiling and melting points.
Water has a high boiling point due to its strong hydrogen bonding
Solvents like ethanol have lower boiling points than water
Melting points of solvents depend on their molecular structure
Some solvents like mercury are liquid at room temperature
Boiling and melting points are important in chemical reactions
