Question

PLEASE HELP! CHEMISTRY! WILL FAN AND MEDAL!
please explain this as easy as possible, i'm super confused! thank you!

4. describe what happens when ag+ combined with na2co3. what does this indicate?

Answer 1

As easy as possible... would be to say that the silver (Ag+) is replacing sodium to form silver carbonate, which would precipitate.

Answer 2

thanks so much!

Answer 3

No problem at all. Want to try write the reaction your self?

Answer 4

Remember to indicate what stays in solution (aq) and what is precipitate (s).

Answer 5

And a big welcome to openstudy btw! :)

Answer 6

i'm just so confused i don't understand the whole formula and reaction solving portion :(

Answer 7

\[\Large \sf Ag^+ (aq) ~+~ Na_2 CO_3 (aq)~ \rightarrow \]
Try write what would be on the right side. I told you that silver carbonate would be formed. Try write that + what ever remains.

Answer 8

Or let me ask like this instead:
What kind of molecule is sodium carbonate (Na2CO3)? Is it a salt or a covalent bound molecule?

Answer 9

@JFraser maybe you can more easy explain the the dissociation of salts by solvation and formation of silver carbonate?

Answer 10

Hmm a salt? I don't know honestly, I'm horrible with this. I did it last year and now I completely forget how to solve them.

Answer 11

Correct it is indeed a salt. So when you solvate a salt in water it dissociate to form ions.
\[\large \sf Ag^+ +2~Na^+ +CO_3^{2-}\]
Now the silver will associate it self with the carbonate and precipitate:¨
\[\large \sf Ag^+ +2~Na^+ +CO_3^{2-} \rightarrow Ag_2CO_3 (s) + Na^+ \]
Note that these reactions are not balanced.

Answer 12

Okay I think I am getting the hang of it from what you just explained. So what would be indicated? That the silver (Ag+) is replacing sodium to form silver carbonate, which would precipitate, like you said?

Answer 13

In principle yes.

Answer 14

Okay! Thank you so much for helping me out with this. I really appreciate it!
