You dissolve this mixture into 100 mL of water and then add an excess of 0.500 M silver nitrate solution. You produce a white solid, which you then collect, dry, and measure. The white solid has a mass of 0.602 g. a. If you had an extremely magnified view of the solution (to the atomic-molecular level), list the species you would see (include charges, if any). (Enter multiple answers as a comma-separated list.) b. Write the balanced net ionic equation for the reaction that produces the solid. Include phases and charges.
