What level of pH indicates the river water to be polluted?
- A.
Zero
- B.
Above 7
- C.
Below 7
- D.
Exactly 7
Correct Answer
C. Below 7Explanation
A pH level below 7 indicates that the river water is polluted. pH is a measure of the acidity or alkalinity of a solution, with 7 being neutral. A pH below 7 indicates that the water is acidic, which can be a sign of pollution. Pollutants such as industrial waste, agricultural runoff, or sewage can lower the pH of the water, making it more acidic. Therefore, a pH below 7 suggests that the river water is contaminated and not in its natural state.Rate this question:

The poisonous gas which reduces the oxygen-carrying capacity of blood to a large extent is:
- A.
SO2
- B.
NO
- C.
CO
- D.
CO2
Correct Answer
C. COExplanation
CO, or carbon monoxide, is a poisonous gas that reduces the oxygen-carrying capacity of blood to a large extent. When inhaled, it binds to hemoglobin in red blood cells, preventing them from carrying oxygen effectively. This can lead to oxygen deprivation in the body's tissues and organs, causing symptoms such as headache, dizziness, and even death in severe cases. CO is produced by the incomplete combustion of carbon-based fuels, such as those found in car exhaust fumes and faulty heating systems. It is important to be aware of the dangers of CO poisoning and take necessary precautions to prevent exposure.Rate this question:

The pH of a sample of water collected from a river is found to be in the range of 3.5 to 4.5. The most likely reason for this is the waste being discharged into the river from a:
- A.
Soap and detergent manufacturing factory
- B.
Car battery manufacturing factory
- C.
Alcohol manufacturing factory
- D.
Plastic cups moulding factory
Correct Answer
B. Car battery manufacturing factoryExplanation
The most likely reason for the pH of the water in the river to be in the range of 3.5 to 4.5 is the waste being discharged from a car battery manufacturing factory. Car batteries contain sulfuric acid, which is highly acidic and can lower the pH of water. Discharging this waste into the river can lead to the acidity levels in the water increasing, resulting in a lower pH value.Rate this question:

Depletion of ground water could be avoided by the:
- A.
Process of afforestation
- B.
Process of deforestation
- C.
Establishing thermal power plants
- D.
Cultivation of high yielding varieties of crops
Correct Answer
A. Process of afforestationExplanation
Afforestation refers to the process of planting trees in an area that has previously been devoid of forest cover. Trees play a crucial role in maintaining the water cycle by absorbing water from the ground and releasing it into the atmosphere through transpiration. By increasing the forest cover through afforestation, the rate of groundwater depletion can be reduced. The roots of trees act as natural filters, preventing water from directly seeping into the ground and instead allowing it to be slowly absorbed. This helps in replenishing the groundwater levels and maintaining a sustainable water supply.Rate this question:
