Name l For the reaction a write the total ionic equation and
     Name l) For the reaction: a) write the total ionic equation and circle the spectator lons. Show charges and the sant to b) Write the rnet ionic equation, including state and charges wbére appropriate Ca(NOs)2 (r each item state and charges whére appropriate  
  
  Solution
Ca(NO3)2 (aq ) + K2SO4 (aq) ----------------> 2 KNO3 (aq) + CaSO4 (s)
total ionic equation :
Ca+2 (aq) + 2 NO3- (aq) + 2 K+ (aq) + SO42- (aq) -------------> 2 K+ (aq) + 2 NO3- (aq) + CaSO4 (s)
spectator ions :
K+ (aq) , NO3- (aq)
Net ionic equation :
Ca+2 (aq) + SO42- (aq) -------------> CaSO4 (s)
