Answer 2

Sodium Nitrite is used as an antidote in cyanide poisoning

Explanation:-

• Sodium nitrate or amyl nitrite can be used in toxic cyanide poisoning conditions. Sodium nitrite is an associate degree chemical compound with the statement NaNO₂. While amyl nitrite is a substance with the formula C₅H₁₁ONO.

• It promotes the formation of methemoglobin (MetHb), which binds CN– ions, forming cyanomethemoglobin. This prevents the repressing action of CN– on complex IV of the electron transport chain.

• Cyanomethemoglobin is then reconverted to methemoglobin by treatment with sodium thiosulphate, forming the less toxic thiosulphate (SCN–). MetHb is converted to oxyhemoglobin with methylene blue.
