    \[{{\text{K}}_{\text{2}}}\text{C}{{\text{O}}_{\text{3}}}\]cannot be prepared by Solvay-ammonia process because

    A)  \[{{\text{K}}_{\text{2}}}\text{C}{{\text{O}}_{\text{3}}}\]is fairly soluble in water

    B)  it has no water of crystallization

    C) \[\text{KHC}{{\text{O}}_{\text{3}}}\] is highly soluble in water

    D)  \[{{\text{K}}_{\text{2}}}\text{C}{{\text{O}}_{\text{3}}}\]decomposes in \[{{\text{H}}_{\text{2}}}\text{O}\]

    Correct Answer: C

    Solution :

    Solvay-ammonia process involves the formation of bicarbonate and bicarbonate of potassium, ie, \[KHC{{O}_{3}},\]is highly soluble in water. Thats why \[{{K}_{2}}C{{O}_{3}}\]cannot be prepared by Solvay-ammonia process.
