Question

what happens when zn granules react with dilute sulphuric acid
a.Bubbles due to colourless odourless gas are formed and tour colourless solution is obtained
b. No reaction takes place
c. Pungent Smelling gas comes out
d. No gas evolved​

Answer 1

Answer - option a

when zinc granules react with dilute sulphuric acid , displacement reaction takes place.

Zn+H2SO4 = ZnSO4+H2

In this reaction hydrogen gas is evolved which is colourless and odourless .

And the colour of the solution changes to colourless.

so option a is correct.
