when zinc metal is added to a dilute solution of a mineral acid, a gas is evolved which is utilised in the hydrogenation of oils. mention the gas evolved. write the chemical equation of the reaction involved. How will you detect the identify of the gas?
Answers
chemistry it is important total within diagram now I am explaining to you in a form of diagram please understand and mark me as a brilliant .
Zinc metal gives hydrogen gas when it is treated with dilute sulphuric acid. Hydrogen gas is utilized in hydrogenation of oil.
Zn+2HCl→ZnCl2+H2
Therefore, the gas evolved is hydrogen.
Test for hydrogen gas: When a burning candle is brought near the hydrogen gas, it burns with pop sound which confirms the presence of hydrogen gas.
