Problem: How many milligrams of sodium sulfide are needed to completely react with 25.00 mL of a 0.0100 M aqueous solution of cadmium nitrate, to form a precipitate of CdS (s)?

FREE Expert Solution
  • Reaction between sodium sulfide (Na2S) cadmium nitrate (Cd(NO3)2) is a double displacement reaction where counterions are being switched
  • Na2S came from Na+ (sodium cation) and S2- (sulfide) while Cd(NO3)2 from Cd2+ (cadmium cation) and NO3- (nitrate)
  • Balanced double displacement reaction will appear as:
