what are the gases liberated when the dilute hydrochloric acid react with. zinc ,and zinc carbonate ,suggest the experiment to identify the gas dry hydrogen chloride gas does not exhibit acid property why
Answers
The gases liberated are hydrogen and carbon dioxide respectively.
When Zinc reacts with dilute HCl acid, the reaction which occurs is shown below.
Zn + 2HCl → ZnCl₂ + H₂
The gas evolved is hydrogen.
If a burning splint is held near the evolving gas, the splint extinguishes with a characteristic 'pop' sound.
When Zinc carbonate reacts with dilute HCl acid, the reaction which occurs is shown below.
ZnCO₃ + 2HCl → ZnCl₂ + H₂O + CO₂
The gas evolved is carbon dioxide.
If a burning splint is held near the evolving gas, the splint extinguishes with a characteristic 'pop' sound.
If the evolving gas is passed to limewater solution, the gas turns it milky.
Dry Hydrogen chloride doesnt dissociate to H⁺ ions thereby not exhibiting acidic property.
Answer:
Explanation:
HELLO DEAR,
The reaction between hydrochloric acid and zinc carbonate.
2HCI + ZnCO3 ---> ZnCl2 + CO2 (g) + H2O
The reaction between hydrochloric acid and zinc.
2HCl + 2Zn -----> 2ZnCl + H2 (g).
I HOPE IT HELP YOU DEAR,
THANKS.
