1. (4pts) When Sodium Chloride (NaCl) is dissolved in water it produces a sodium ion (Na+) and a chloride ion (Cl-). Similarly, when silver nitrate (Ag(NO3)) is dissolved in water, it produces a silver ion (Ag+) and a nitrate ion (NO3-). When Ag+ and Cl- are in the same solution, they join to form a solid AgCl. This formation of a solid is called precipitation. The chemical reaction can be written: Ag+(aq) + Cl-(aq) <==> AgCl(s) The Na+ and NO3-, while present in solution, do not participate in the reaction. They are referred to as spectator ions. In the stockroom, you will find two solutions: AgNO3 solution: This was formed by dissolving 1.00g of AgNO3 in 100.0 ml of water. NaCl solution: This was formed by dissolving 0.50g of NaCl in 100.0 ml of water. a) (1pts) Calculate the concentration of Ag+ and NO3- in the AgNO3 solution. Please show your work, and check your result against the virtual lab. (Note that [X] is shorthand notation for the concentration of X in M (moles/l).) b) (1pt) Calculate the concentration of Na+ and Cl- in the NaCl solution. Please show your work, and check your result against the virtual lab. c) (2pts) When the above two solutions are mixed together, calculate the amount of AgCl produced (in grams). Also calculate the concentrations of the ions remaining in solution. Please show your work and check your answers against the virtual lab.
