Question

explain with proper example reaction of acid and bases with metals
​

Answer 1

Answer:

When a metal reacts with an acid, it generally displaces hydrogen from the acids. This leads to the evolution of hydrogen gas. The metals combine with remaining part of acids to form a salt. For example reaction of sulphuric acid with zinc.

H2SO4 + Zn → ZnSO4 + H2

Alkalis (bases that are soluble in water) react with the metal to produce salt and hydrogen gas. For example reaction of zinc with sodium hydroxide.

2 NaOH + Zn → Na2ZnO2 + H2

Answer 2

Answer:

• When an acid reacts with metal,  salt and hydrogen are produced:

acid + metal → salt + hydrogen

> example - nitric acid + calcium → calcium nitrate + hydrogen

• Bases also react with certain metals like zinc or aluminum for example to produce hydrogen gas.

> example sodium hydroxide reacts with zinc and water to form sodium zincate and hydrogen gas.
