What test was performed to identify hydrogen gas? write a balanced equation to represent this test?
Answers
Hydrogen burns with a popping sound,
As for the equation, my guess would be:
2H2 + O2 ---> 2H2O Hydrogen: A lit splint held to an inverted try-tube of gas.Hydrogen will burn with a squeaky pop! Oxygen: place a gleaming splint right into a try-tube of unknown gas- if the splint relights, you have examined for oxygen. Carbon Dioxide:you will require LIME WATER. (Calcium hydroxide in water) bubble the gas for the period of the lime water, carbon dioxide will turn the lime water white/ milky. it is due a white precipitate stated as calcium carbonate yet whilst greater carbon dioxide is bubbled by way of, the precipitate "disappears". (The calcium carbonate reacts with greater carbon dioxide to style calcium hydrogen carbonate that's soluble in water.) Ammonia: try using ammonia and water answer and centred hydrochloric acid. A white smoke is produced. it is tiny debris of ammonium chloride. Chlorine: The try is to place a chew of damp litmus paper right into a tube of the unknown gas, if the paper is bleached, you have examined for chlorine. For secure practices motives please determine that this try is performed in a fume cabinet!!
