Does manganese chloride and cadmium acetate precipitate when mixed

Answer 1

No, there will be no precipitate formed. Both are soluble and dissociate forming the respective ions. None of the possible products are insoluble, so there is NO REACTION.

MgCl₂(aq) + Cd(C₂H₃O₂)₂(aq) ==> no reaction

You have Mg²⁺, Cd²⁺, Cl^-, and C₂H₃O₂^- ions, and all possible products are soluble.
