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.

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

Water content mechanism can be found through various methods and is important for various reasons.
Water content can be measured through techniques such as gravimetric analysis, Karl Fischer titration, and moisture analyzers.
Water content is important in industries such as food, pharmaceuticals, and cosmetics to ensure product quality and stability.
Water content is also important in environmental studies to understand t...
Developing HPLC methods involves selecting appropriate columns and optimizing parameters.
Choose a suitable column based on the analyte's properties and the separation goal.
Optimize parameters such as mobile phase composition, flow rate, and temperature.
Validate the method by assessing its selectivity, sensitivity, accuracy, and precision.
Common column types include C18, C8, and phenyl.
Other factors to consider include ...
Carbon loading in column refers to the amount of carbon used in the stationary phase of a chromatography column. Endcapping is a process to block the remaining silanol groups on the surface of the stationary phase.
Carbon loading is typically expressed as a percentage of the total weight of the stationary phase.
Higher carbon loading can improve the selectivity and retention of certain analytes.
Endcapping is important to...
