how do bases and metal react?
Asked by wierdtechs | 16 Jul, 2018, 08:50: PM
answered-by-expert Expert Answer

 All metals do not react with the base, only amphoteric nature metals react with both base and acid 

When alkali or base reacts with metal, it produces salt and hydrogen gas.

 Alkali + Metal → Salt + Hydrogen

Example: Zinc metal reacts with the base to give sodium zincate and hydrogen gas.
