✔When Zinc granules are  taken in a beaker and sodium hydroxide (alkali )solution is added to it, Sodium zincate is formed and bubbles of Hydrogen gas are evolved. 

✔The chemical reaction taking place is 
Zn(s)+ 2NaOH (aq) →   Na2ZnO2 (aq) + H2(g)

✔[In this reaction Zn being an amphoteric metal acts as an acid which reacts with a base.
