Test for Cl- is not complete in the table. We still need to add NH3 in excess. The PPT formed after the addition of AgNO3 will dissolve. Please let's take this correction

They did not ask us to provide silver nitrate in the materials so definitely we don't need to add that part

Read the instruction number 3 carefully. It reads " The usually apparatus and reagents for qualitative work including the ones they listed in your specimen paper. AgNO3 is one of the usual chemicals used for qualitative analysis so should be included. So my advice to you is to include it in your analysis. If it did not come out, you still have nothing to lose.
