Question 42

Acids, Bases and Salts

Which of the following is a neutralization reaction?

A.Addition of sodium chloride solution to potassium chloride solution
B.Addition of trioxonitrate (V) acid (nitric acid) to distilled water.
C.Addition of trioxonitrate (V) acid (nitric acid) to tetraoxosulphate (VI) acid (sulphuric acid).
D.Addition of trioxonitrate (V) acid (nitric acid) to potassium trioxonitrate (V) (potassium nitrate) solution
E.Addition of trioxonitrate (V) acid (nitric acid) to potassium hydroxide solution.

Show the answer and explanation

Answer: E (Addition of trioxonitrate (V) acid (nitric acid) to potassium hydroxide solution.)

Explanation

Only E is an acid reacting with a base: HNO₃ + KOH → KNO₃ + H₂O.
