You are given a 1.50g mixture of sodium nitrate and sodium chloride. 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 0.641g. a) if you had an extremely magnified view of the solution, list the species you would see b) write the balanced net ionic equation for the reaction that produces the solid. Include phases and charges. c) calculate the percent sodium chloride in the original unknown mixture.
