UmL 36. For the reaction between 200.0 mL of 0.100 M silver nitrate and 95.00 mL of 0.100 M sodium chloride, the concentration of the silver ions in solution after the reaction is complete is: a. 0.00 M. All of the silver ions are used to make the precipitate. b. 0.100 M. The silver ions do not participate in the chemical reaction and are considered spectator ions. c. greater than 0.100 M. For every 1.0 mol of silver nitrate there are 2.0 mol of silver ions in the solution. d. less than 0.100 M. Even though silver ions do not react, they are diluted when mixed with the sodium chloride solution. e. less than 0.100 M. Some, but not all, of the silver ions are used to make the precipitate.
