Hello,

When an acid interacts with a metal, it produces a salt and hydrogen:

acid + metal ----->salt + hydrogen

The type of salt formed is determined by which acid and metal react.

When sodium metal interacts with hydrochloric acid, hydrogen gas and sodium chloride are produced.

2Na(s)+2HCl(aq)→2NaCl(aq)+H ₂ (g)

Na metal and hydrochloric acid are the reactants.

Hydrogen gas and salt chloride solution are the end products.

Hope you got it

Thank you
