Assertion (A): A reaction between an acid and a base is called a neutralization reaction. Reason (R): Neutralization always produces a neutral solution with pH exactly 7.
A. A is false, but R is true
B. A is true, but R is false
C. Both A and R are true, and R is the correct explanation of A
D. Both A and R are true, but R is not the correct explanation of A
Answer: Option B
Solution (By JKSSB Mock Tests)
Neutralization is the reaction of an acid with a base to produce salt and water. However, the resulting solution is not always neutral (pH 7) because the salt may undergo hydrolysis. If the acid is strong and base weak (e.g., HCl + NH₄OH), the salt (NH₄Cl) is acidic, pH < 7. If acid is weak and base strong (CH₃COOH + NaOH), salt is basic, pH > 7. Only strong acid-strong base gives pH 7.
