Question

The automobile emission can be reduced by adding which of the following in the petrol?

• B. Cadmium salts
• C. Cobalt salts
• D. Silicon 011

Answer 1

The correct option is A Barium salts

The combustion of the fuel in the automobiles result in the production of emissions which contains toxic gases. The use of barium salts help in the reduction in the emissions from the burning of the fuels like petrol and diesel. However, the emissions which are released along with the barium salts have toxic effects on ingestion. The use of alkali metal salts like sodium, calcium, magnesium, potassium, etc which do not cause any effect are been used nowadays.

Thus, the correct answer is option A.
