Aditya Birla Group Team Lead Operations Interview Questions and Answers

The value of water pH indicates its acidity or alkalinity.

• Water pH is a measure of how acidic or alkaline the water is.

• The pH scale ranges from 0 to 14, with 7 being neutral.

• A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity.

• Pure water has a pH of 7.

• Different substances can affect the pH of water, such as pollutants or minerals.

40% of 800 is 320.

• Calculate 40% of 800 by multiplying 800 by 0.4.

• 40% of 800 = 800 * 0.4 = 320.

1 kilogram is equal to 0.001 metric tons.

• 1 kilogram = 0.001 metric tons

• To convert kilograms to metric tons, divide by 1000

• Example: 5 kilograms = 5 * 0.001 = 0.005 metric tons

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

• pH below 7 indicates acidity, with 0 being the most acidic

• pH above 7 indicates alkalinity, with 14 being the most alkaline

• Pure water has a pH of 7, considered neutral

Water properties include cohesion, adhesion, high specific heat, universal solvent, and density anomaly.

• Cohesion: Water molecules stick to each other due to hydrogen bonding.

• Adhesion: Water molecules stick to other substances due to polarity.

• High specific heat: Water can absorb a lot of heat before temperature changes.

• Universal solvent: Water can dissolve many substances due to its polarity.

• Density anomaly: Water is mo
