Question

What two products are formed when a base is neutralized by an acid?

Answer 1

Hint: If the base has hydroxyl ion then the hydrogen ion of the acid and hydroxyl ion of the base will combine a product. One of the products will be a compound in which the opposite ions of the acid and base will combine.

Complete answer:
We know that the acid is a substance in which hydrogen ions are present and this hydrogen atom can be dissociated when dissolved in water or when a base is added into it, or other definition says that acid is a substance having the ability to accept a pair of electrons. In the same way, we can say that a base is a substance in which hydroxyl ions are present and this hydroxyl ion can be dissociated when dissolved in water or when an acid is added into it, or other definition says that a base is a substance having the ability to donate a pair of electrons.
Usually when an acid and a base react with each other then a neutralization reaction takes place and then there is a formation of salt if the base is having the hydroxyl ion the other product will be a water molecule. For example, when the hydrochloric acid and sodium hydroxide reacts then the salt formed is sodium chloride and water. The reaction is given below:
$HCl+NaOH\to NaCl+{{H}_{2}}O$

Note:
If the base doesn't have a hydroxyl ion then there is the only formation of salt, for example, when ammonia and hydrochloric acid react then only ammonium chloride is formed. The reaction is given below:
$N{{H}_{3}}+HCl\to N{{H}_{4}}Cl$
