    The given reaction belongs to which kind of chemical reaction? \[\underset{Spdoium\,sulphate}{\mathop{N{{a}_{2}}S{{O}_{4}}(aq)}}\,+BaC{{l}_{2}}\xrightarrow{{}}\underset{Barium\,sulphate}{\mathop{BaS{{O}_{4}}(s)}}\,+2NaCl(aq)\]

    A) Combination reaction

    B) Decomposition reaction

    C) Displacement reaction

    D) Double displacement reaction

    Correct Answer: D

    Solution :

    \[N{{a}_{2}}S{{O}_{4}}+BaC{{l}_{2}}\to BaS{{O}_{4}}+2NaCl\] The above reaction is a double displacement reaction as there is mutual exchange of radicals between two compounds.
