Question

Using the three criteria for double displacement reactions. and the solubility table, predict whether a double displacement reaction will occur for each of the following If the reaction will occur, balance the reaction write conventional, total ionic and net ionic equations Box the net ionic equation. Be sure to include the proper phase labels. If no reaction will occur write "no reaction". All reactants are aqueous solutions. Potassium sulfide and copper (II) sulfate rightarrow. Aqueous ammonia and oxalic acid rightarrow Potassium hydroxide and ammonium chloride rightarrow.

Explanation / Answer

Reaction:

H2C2O4 + NH4OH ==> (NH4)2C2O4 + H2O

Half-Reactions:

(2H+ + C2O42-) + (NH4+ + OH-) ==> (2 H+ + OH-)+ (NH4+ + C2O42-)

Balanced:

H2C2O4 + 2NH4OH ==> (NH4)2C2O4 + 2H2O

Methatesis reaction of neutralization!
