You are given a 1.50 g mixture of sodium nitrate and sodium chloride. You dissolve this mixture into 100 ml of water and then add an excess of .500 Molar silver nitrate solution. You produce a white solid, which you then collect, dry, and measure. The white sand has a mass of .641 g.
a. List the species you would see if you had a magnified view of this solution
b. White the balanced net ionic equation for the reaction that produces the solid.
c. Calculate the percent sodium chloride in the original unknown mixture.
For question A: I believe the species are Na+, Cl-, and NO3-.
I am not sure about question B because I don't know what they mean by net ionic reaction. My guess at what the formula would be is:
NaCl + NaNO3 ------> NaNO3 + NaCl
But I don't think that this is the reaction that produces the solid. Actually is it a reaction that produces the solid; isn't the solid just the leftover silver nitrate that didn't react. I'm not sure.
I am pretty much stumpted on Question C. I would appreciate any sort of help on this question. Thanks.
