Balanced equation: 
<span>CaSO4(aq) + AgNO3(aq) -> Ag2SO4(s) + Ca(NO3)2(aq) 

</span>Twice the amount of silver is needed than SO4 in order to precipitate. Silver would be the limiting reagent (from AgNO3). 
Find the leftover concentration of CaSO4 by subtracting  the amount that reacted with the silver. 
<span>
∴[CaSO4]=[Ca^2+]=0.0500M-0.0390M= 0.0110 M </span>

  • the formation of a gas, which might be visible through bubbles being produced
  • a temperature change - often the chemical reaction will produce heat
  • the formation of a precipitate - this means that particles that do not dissolve in the solution will form
