Testing for Cl-
When you add 1mL of NaCl, 1mL of 6 M HNO3, and 3 drops of 0.1 M of AgNO3. When you test for ions why are ions present? I also conducted the experiment using an unknown and got the same results for both.
Testing for Fe^3+
Fe(NO3)3, 5 drops of 0.1 M KCNS why are ions present when you mix those solutions? I also conducted the experiment using an unknown and got the same results for both.
