Aarti Industries Production Supervisor Interview Questions, Process, and Tips

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

• pH stands for 'potential of Hydrogen'

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline

• Examples of pH levels: Battery acid (pH 1), Lemon juice (pH 2), Pure water (pH 7), Baking soda (pH 9)

Strong alkali refers to a substance with a high pH level that can cause severe burns and irritation to skin and eyes.

• Strong alkalis have a pH level above 10

• They are highly corrosive and can cause severe burns on contact with skin

• Examples include sodium hydroxide (caustic soda) and potassium hydroxide

Implemented lean manufacturing processes to improve efficiency and reduce waste.

• Introduced Kanban system to streamline production flow

• Implemented 5S methodology to organize workspaces and improve productivity

• Utilized Kaizen events to continuously improve processes

• Trained employees on standard work procedures to ensure consistency

• Analyzed production data to identify bottlenecks and implement solutions

Chemical reactions involve the breaking and forming of chemical bonds to create new substances.

• Chemical reactions can be classified as exothermic (release heat) or endothermic (absorb heat).

• Reactants are the substances that undergo a chemical change, while products are the new substances formed.

• Chemical reactions can be represented by chemical equations, showing the reactants and products involved.

• Factors such as tempe...read more
