what happens when zinc granules are added to sulphuric acid? write any two observations and support it with a balanced chemical equation. please answer need it urgently.
Answers
Answer:
When dilute sulphric acid reacts with zinc granules, then zinc sulphate and hydrogen gas are formed. Zinc being more reactive than hydrogen, displaces it from sulphuric acid. This liberated hydrogen is evolved as hydrogen gas. When zinc reacts with dilute sulphuric acid hydrogen gas is evolved, with an effervescence.
Observations- 1) When dilute sulphuric acid is poured on zinc granules, then zinc sulphate is formed along with the evolution of a gas. Zinc is more reactive than hydrogen, so displaced it from sulphuric acid.
observation 2:gas evolved is hydrogen. ... Only hydrogen gas burns with a 'pop' sound.
HOPE IT HELPS....
Answer:
Explanation:
When zinc granules are added to sulphuric acid it will result in
Zn+H2SO4--------------ZnSO4+H2
to test that hydrogen gas is liberabed bring a buring matchstick near it and it put off with poop sound
sorry if any mistakes
