Answer: (B) Double displacement
Explanation:
A redox reaction is not a double displacement reaction. This is because in a double displacement reaction, two ionic species interact to produce products, and there is no loss or gain of electrons.
When a portion of two ionic compounds is transferred to form two new components, this is known as a double displacement reaction. This is the pattern of a twofold displacement reaction.
The ions precipitate and exchange ions in double displacement processes, which occur predominantly in aqueous solutions.
Examples of double displacement reaction:
- H2SO4 + 2LiOH → Li2SO4 + 2H2O
- AgNO3 + HCl → AgCl + HNO3
- 2NaCl + CaSO4 → Na2SO4 + CaCl2
- AgNO3 + NaCl → AgCl + NaNO3
