When a solution of AgNO3 is mixed with a solution of NaBr (multiple options could be correct):

1) NaNO3 precipitate will spontaneously form.


2) After a few minutes pass, the concentration of Ag+ and Br- will be lower than when the two solutions were first mixed.


3) After a few minutes pass, the concentration of Ag+ and Br- will be the same as when the two solutions were first mixed


4) The concentration of Ag+ and Br- are momentarily greater than in a saturated solution of AgBr.


5) AgBr precipitate will spontaneously form.
