Barium chloride on reacting with ammonium sulphate forms barium sulphate and ammonium chloride. Which of the following correctly represents the type of the reaction involved? (i) Displacement reaction (ii) Precipitation reaction (iii) Combination reaction (iv) Double displacement reaction
A
Only(i)
B
Only (ii)
C
Only (iv)
D
`(ii) and (iv)`
Text Solution
Verified by Experts
The correct Answer is:
D
The reaction is a double displacement reaction as follows `underset("chloride")underset("Barium")(BaCl_(2))+underset("sulphate")underset("Ammonium")((NH_(4))_2SO_(4))rarrunderset("(White ppt.)")underset("sulphate")underset("Barium")(BaSO_(4))darr+underset("chloride")underset("Ammonium")(2NH_(4)Cl)` It is also called precipitation reaction due to the formation of white precipitate of barium sulphate.
