The salts produced in the given neutralization reactions are
.
Further Explanation:
Neutralization reaction:
It is the reaction that occurs between an acid and a base in order to form salt and water. It is named so as it neutralizes the excess amount of hydrogen or hydroxide ions present in the solution. It is used to decrease the acidity in the stomach, wastewater treatment, antacid tablets and to control the pH of soil. An example of neutralization reaction is,

(A)
is a strong acid while KOH is a strong base.
The dissociation of
occurs as follows:

The dissociation of KOH occurs as follows:

The
ions released by
combines with
ions of KOH and water is formed. So
and
combine with each other and form salt
.
(B)
is a strong acid while
is a strong base.
The dissociation of
occurs as follows:

The dissociation of
occurs as follows:

The
ions released by
combines with two
ions of
and two moles of water are formed. So
and
combine with each other and form salt
.
The complete reaction is as follows:

(C) HCl is a strong acid while
is a strong base.
The dissociation of HCl occurs as follows:

The dissociation of
occurs as follows:

The
ions released by HCl combine with
ions of
and water is formed. So
and
combine with each other and form salt
.
The complete reaction is as follows:

(D) HCl is a strong acid while KOH is a strong base.
The dissociation of HCl occurs as follows:

The dissociation of KOH occurs as follows:

The
ions released by HCl combines with
ions of KOH and water is formed. So
and
combine with each other and form salt
.
The complete reaction is as follows:

So salts formed in all the reactions are
respectively.
