Understanding Water Quality and pH

Front

What is the pH scale used to measure?

Back

Acidity or alkalinity

Front

Which pH value is considered neutral?

Back

7

Front

How does a low pH level affect aquatic organisms?

Back

Causes stress or death

Front

Why is dissolved oxygen important for aquatic life?

Back

It is essential for respiration

Front

Which of the following is a water quality indicator? pH level, Air pressure, Soil type, Wind speed

Back

pH level

Front

What is the effect of pollutants on water quality?

Back

Degrades quality

Front

Explain how the pH scale is structured and what each end of the scale represents.

Back

The pH scale ranges from 0 to 14, with 0 being highly acidic, 7 neutral, and 14 highly alkaline.

Front

Describe a scenario where a change in pH could affect an aquatic ecosystem.

Back

A sudden increase in pH due to industrial discharge can lead to the death of fish and other aquatic organisms.

Front

How can human activities lead to changes in dissolved oxygen levels in water bodies?

Back

By increasing water temperature through industrial processes, which reduces the amount of dissolved oxygen.

Front

Discuss the relationship between water temperature and dissolved oxygen levels.

Back

As water temperature increases, dissolved oxygen levels decrease.
