Question

What are the gases liberated when dilute hydrochloric acid react with zinc and zinc carbonate suggest the experiment to identify these gases

Answer 1

Answer:

2HCl(dilute) +Zn ---> ZnCl2 +H2( gas upward arrow)

2HCl+ZnCO3--->ZnCl2 +H2O +CO2(upward arrow gas)

Explanation:

H2 burns with a pop sound when a burning splint is brought near it

CO2 turns lime water milky but has no effect on acidified K2Cr2O7 or acidified KMnO4

H2O turns Custom(anhydrous) blue

And it also turns blue CoCl2 paper to pink
