1. Write net-ionic equations for all the reactions occurring in the Group I analysis for each cation in the group (regardless of which ions were present in your particular unknown). Write all the reactions for silver, then all those for mercury, then all those for lead. Show the physical form of all species (eg., (s), (aq), etc.). Underline all solids. Silver: Mercury: Lead: 2. In Step 5 of the procedure ("Test for Silver"), you were told to add 6MHNO3 "until acidic to litmus." Explain why it is important to add enough 6MHNO3 to make the solution acidic in order to get a positive test
