Problem: Enter a balanced equation for the reaction of Na2S and CdSO4.

FREE Expert Solution
  • Reaction between this compound is a double displacement reaction where counterions are being switched

  • Na2S (aq) will dissociate as Na+ (aq) and S2- (aq) while CdSO4 (aq) as Cd2+ and SO42- (aq). Recall that for ionic compounds, the charge of the ion goes to the subscript of the counter ion

  • Switching the counterions, products will appear as: Na2SO4 and CdS. 

  • In aqueous media, we need to determine if the products will  be soluble (aq) or insoluble (s) by using the solubility rules
