It is chloride which forms silver chloride.
Silver nitrate and lead nitrate do not react, so there would be no precipitate.
Add silver nitrate. If it is present it forms a yellow precipitate
conclusion of silver nitrate and sodium hyroxide
Silver nitrate does not precipitate in this case; elemental silver does. In this reaction, silver nitrate reacts with copper to form elemental silver and copper II nitrate. The silver, which is a metal, is insoluble in water.
The nitric acid reacts with other ions that might precipitate with silver nitrate. Doing this first gets these other unwanted precipitates out of the way. If you are testing with Fluoride as your halide remember that silver nitrate does not precipitate with Fluoride, so no precipitate does not mean that halide ions are not present.
Silver nitrate and lead nitrate do not react, so there would be no precipitate.
Add silver nitrate. If it is present it forms a yellow precipitate
an example of a precipitate is: silver nitrate + sodium chloride = silver chloride and sodium nitrate the precipitate is the silver chloride it forms a white powder

Potassium nitrate and a precipitate of Silver iodide are formed
Silver Nitrate is soluble.
Produces Silver iodide precipitate and Sodium nitrate
When silver nitrate reacts with hydrochloride a white precipitate of Silver Chloride is formed.
If you add iodide (iodine ions) to Acidfied Silver Nitrate, a pale yellow precipitate is formed. This precipitate is Silver Iodide (AgI).
Silver Chloride (AgCl) is the precipitate in this reaction.
