What happens if i combine AgNO3(aq) with NaCl(aq) followed by addition of conc. aqueous ammonia? What is the reaction?
I know that the reaction without ammonia is
NaCl(aq) + AgNO3(aq) --> NaNO3(aq) + AgCl(s)
Just don't know the what happens in the presence of ammonia.

Ahhh, chemistry. The bane of my existance

H2 + 02 = H20

Complex ions????

Thats jewish bullshit.

This equation is unbalanced. The correct answer is
2H2 + O2 = 2H2O

Precipitate is dissolved by formation of the diammine complex [Ag(NH3)2]+

Yeah, we are doing coordination compounds

you get ammonia chloride

AgNO3(aq) + NaCl(aq) => AgCl(s) + NaNO3(aq) AgCl(s) + 2 NH3(aq) => [Ag(NH3)]+(aq) + Cl-(aq) [Ag(NH3)]+(aq) + KBr(aq)

This

Damn, how do you know the ammonia replaces the chlorine

Well aqueus ammonia is a stong lewis base so I think it will bond with the lewis acid which is NO3. So you will get dissociated Na+, OH- and NH4NO3. AgCl is way too strong of a bond to get affected by the ammonia.

A complex forms

Where do you get the potassium bromide from?

Sorry, copied too far along the equation. Had this exact question in one of my old test banks but it goes further to describe what happens when we add the KBr solution.

Oh right, cheers for the help! So it would be the same process if it was AgNO3(aq) with KI(aq) , except change Na with K and Cl with I?

Because this complex is highly favoured. Further details are pretty complicated.

Yes which is indicated by their similar relative electronegativity.

Oh right. I'm sure we will learn more about why ammonia would be favoured over a halide later in the course.

There need to be two ammonium in the silver. It's a metal complex.

That makes sense, also it wouldn't be balanced otherwise

This is super wrong. Silver is not 2+ but 1+ and also there are two NH3 at Ag.

Yes but don't look at balance. Correct reaction is more important in the first place, then balance.

Oh shit you’re right. God damn it, I’ve been using this test bank for 3 years.

Thank you! I changed it

Reaction of aqueous Ni(II) with pyridine
would the complex just be [Ni(py)6]

i forgot 2+ at the end

Ni(II) + py --> [Ni(py)6]

Chemistry is so retarded. It's all rote learning. Intuition plays no part
