Answer:
Option c
Explanation:
➝This is a double displacement reaction.
➝In this reaction Calcium Hydroxide displaces Nitrate from Nitric acid.
➝Nitric Acid displaces Hydroxide from calcium Hydroxide.
➝This is a neutralisation reaction
➝Nitric acid is a strong acid.
➝Calcium Hydroxide is a Alkali or Strong base.
➝Hence both neutralises each other.
HNO3 + Ca(OH)2 → Ca(NO3)2 + 2H2O is an example of (ii) neutralization reaction and (iii) double displacement reaction.
Answer: c) (ii) and (iii)
