A sample of water was tested with AgNO3, and gave a white precipitate.
A.What ion was most likely present?
B.What chemical would be the most likely source for the ion?
So far I have that Chloride ion was most likely present and detected by AgNO3, but I don't understand what B is asking me...can someone explain? Thx

I would think that since Cl2 is added as a bactericide for many public water supplies that the Cl2 might be a source (from its reaction with H2O and any bacteria) of chloride ion.
