Question

Drescribe the reaction of metals with acids

Answer 1

$\bold\pink{\underline{AnswEr:-}}$

Metal + acid → Salt + hydrogen

When metal reacts with acid, a salt and hydrogen gas is produced. This depends on where the metal present in reactivity series. The fastest reaction between metal and acid takes place when the metal present how high up in reactivity series.

$\large\bold{\underline{\boxed{\sf{\red{For \; example :-}}}}}$

★ Reaction between Sodium(Na) with Hydrochloric acid (HCL), Sodium chloride (NaCl) and hydrogen (H2) is produced :-

$2Na(s) + 2HCl(l) → 2NaCl(l) + H2(g)$

Answer 2

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$

Metals on reaction with acid result in the formation salt and hydrogen gas.

General Reaction :-

Acid + Metal → Salt + Hydrogen

Example :-

Ca + H2SO4 → CaSO4 + H2↑

★ The salt that is produced depends upon which acid and which metal react.
