Regarding precipitation (attempts shown)
« on: November 08, 2018, 12:11:31 AM »

Heres the question,
What happens when 6M nitric acid is added to an
Aqueous solution that contains 0.1M Cl - and 0.1M Ag(NH3)2 +?

The answer is that a precipitate of AgCl forms

First off i thought why wouldnt the silver complex react with the chlorine ion,
Then i try to write out the possible products coming out
Of this ,which is AgNO3 and HCl?
Then im stucked cuz no options resembles what ive got so far..thus stucked..

Whyyyy please explain

Try to list all ions/molecules present in the solution, see if there are some that will obviously react witch each other, shifting equilibria.

I did, but couldnt see what might and why,
though my instincts tell me Ag and Cl will form ppt,but then theres this NH3 bugging there, so dont quite understand what this reaction is about

You have nitric acid, you have ammonia. What will happen?
