In activity 2.3 on page 19 ( NCERT Science textbook for class 10 ) ,what do u observe on d surface of zinc granules?

Answer 1

You will observe the layer of displaced element from the solution with which Zinc granules are reacting.

And next time when you write question,do not give address of your book,all here are not of class 10,some are of class 11,some are of class 12,and some are class 12 pass out like me.
