    never mind you just take the precipitate made from each reaction and look at the one that was insoluble in water. eg
    Lithium Chloride + Potassium carbonate -> lithium carbonate ( the presumed precipitate) and potassium Chloride
    whatever the carbonate was attached to I had to check it was insoluble.

    The only insoluble one was Calcium Carbonate. (B)
