Properties of CO

Q. Carbon monoxide acts as a good reducing agent. Explain.

Q.

Is CO binding to hemoglobin reversible?

Q.

State the poisonous nature of carbon monoxide.

Q.

Why is carbon monoxide called the silent killer?

Q.

Oxygen Toxicity is associated with which of the following

1. Failure of ventilation of Lungs

2. Blood Poisoning

3. The collapse of the alveolar wall

4. Both B and C

Q.

When a man inhales air containing normal concentration of O₂ as well as CO he suffers from suffocation because:

1. CO reacts faster with haemoglobin and products cannot dissociate

2. CO reacts with oxygen which is thus removed from the air reaching the lungs

3. CO affects vagus nerves

4. CO affects the diaphragm and intercostal muscles

Q.

For which of the following gas, Haemoglobin has the maximum affinity?

1. Carbon monoxide $\left(CO\right)$

2. Oxygen $\left(O_2\right)$

3. Carbon dioxide $\left(C{O}_2\right)$

4. Hydrogen $\left(H_2\right)$

Q.

Explain the reducing action of carbon monoxide.

Q.

2. Increased precipitation of calcium carbonate
3. Decreased pH
4. Decreased salinity

Q. Carbon monoxide is a pollutant because it

1. Inhibits glycolysis
2. Combines with haemoglobin
3. Inactivates nerves
4. Combines with oxygen

Q.

What is pollutant?

Q. If man inhales normal concentration of oxygen but also same concentration of CO; he suffers from suffocation because

1. CO reacts with oxygen which is thus removed from air reaching the lungs.
2. CO affects diaphragm and intercostal muscles.
3. CO reacts faster with haemoglobin and products cannot dissociate.
4. CO affects vagus nerves.
