Question

Which of the following describes the correct net ionic equation for the reaction of copper (II) chloride solution with silver nitrate solution?
Select one:
a. CuCl2 (aq) + AgNO3 (aq) ---> Cu(NO3)2 (aq) + AgCl (s)
b. CuCl2 (aq) + 2AgNO3 (aq) --->Cu(NO3)2 (aq) + 2AgCl (s)
c. Cu2+ (aq) + 2Cl- (aq) + 2Ag+ (aq) + 2NO3- (aq) --->Cu2+ (aq) + 2NO32- (aq) + 2AgCl (s)
d. 2Cl- (aq) + 2Ag+ (aq) --->2AgCl (s)

Answer 1

"net" means you remove all the spectator ions and other species which are not directly reacting

Answer 2

Ok. Could you give me an example of a spectator ion. :) Thanks!

Answer 3

hm basically, if they remain aqueous through out the reaction, they're spectator ions

Answer 4

like NaCl (aq) + AgNO3 (aq) -> AgCl (s) + NaNO3 (aq)

NO3- and Na+ are spectator ions

Answer 5

Alright. I'm still confused. :P So the spectator ions are the ones that are on the products side next to the aqueous sign?

Answer 6

they spectator ions are the ones what do not react (e.g. form a precipitate)

for example, if you write NaCl (aq), it means that they're in aqueous solution and are not bound, you could also write them like this: Na+ (aq) + Cl- (aq)

Answer 7

Is it d because that is the only product that does not have a solution?
