Question

Antidote for carbon monoxide is:
A.Carborundum
B.Carbogen
C.Carbonic acid
D.Pure oxygen

Answer 1

Hint: Carbon monoxide is a poisonous gas, it basically dissolves in blood and removes oxygen from it and thus kills a person, therefore an antidote is required which is made up from the combination of carbon dioxide and oxygen.

Complete step by step answer:
An antidote is a substance which works against the poison or we can say an antidote is a substance which works in an unwanted situation to make it better.
Carbon – monoxide is a gas composed of two elements carbon and oxygen in $1:1$ ratio. It is chemically represented as ${\text{CO}}$ . It is a colourless and odourless gas which is harmful for humans, this gas can even kill a person.
It is mostly produced by trucks, cars, jeep or burning substances such as stoves, fireplaces, etc.
The inhalation of carbon monoxide gas causes some symptoms that tell us that it is poisoning our body. These symptoms are weakness, vomiting, body pain etc.
It basically kills a person if he/she inhales it a lot.
The poisoning starts in the human body when the carbon monoxide reaches the blood. The $CO$ gas has more tendency to bind with red blood cells (RBC) that’s why carbon monoxide replaces the oxygen from the blood and itself moves along with the flow of red blood cells.
That’s why an antidote is required to save lives and this antidote is a carbogen which is composed of carbon dioxide and oxygen in \[1:19\] ratio.
Hence option (B) is correct.

Note:
The spreading of carbon monoxide in the human body leads to tissue damage and due to excessive inhalation of carbon monoxide a person dies. So to protect a person use antidote or carbon monoxide detectors.
