Question

explain the reaction of various metals with acids with suitable examples

can someone answer ??

Answer 1

Reactions of acids and alkalis

Acids

Common acids include:

hydrochloric acid, HCl

sulfuric acid, H2SO4

nitric acid, HNO3

Acids produce hydrogen ions, H+, when they dissolve in water.

Alkalis

Common alkalis include:

sodium hydroxide, NaOH

potassium hydroxide, KOH

calcium hydroxide, CaOH

Alkalis produce hydroxide ions, OH-, when they dissolve in water.

Neutralisation

Alkalis neutralise acids. An indicatoris used to identify the point when neutralisation is reached.
During the reaction, hydrogen ions from the acid react with hydroxide ions from the alkali to form water:
H+(aq) + OH-(aq)  H2O(l)

Salt formation

When an acid reacts with a metal hydroxide, a salt and water are produced:
acid + metal hydroxide  salt + water
The name of a salt has two parts:

the first part comes from the metal in the metal hydroxide

the second part from the acid used
