Ag2CO3(s) <==> 2Ag+(aq) + CO32-(aq)
The CO32- reacts with H2O to form H2CO3 which ionizes to H+ + HCO3-
Ag2CO3(s) <==> 2Ag+(aq) + CO32-(aq) + H2CO3(aq) <==> H+ + HCO3-
Mass balance
[Ag+] = 2[CO32-] + [HCO3-] + [H2CO3]
(note: you may be required to include H3O+ and OH-)

The carbonate (CO3^2-) will react with H2O to form H2CO3. I’ll amend the original answer.

It still is not marking it as correct but thank you for trying!

Yes, it is very picky and I can't seem to figure out the correct answer but thats okay

You might consider adding H2O + OH- to the above equation and put all in brackets just a suggestion. If that doesn’t work, I’m out of ideas.

Lizzi…I am going to amend previous answer and comments because I didn’t fully read the question and missed the main point of using MASS BALANCED equation.

This is not correct, but this is the hint I received after submitting this response: Ag2CO3 dissolves in water according to the reaction: Ag2CO3(s)↽−−⇀2Ag+(aq)+CO2−3(aq) If the carbonate ion in solution did not react with water and remained as CO2−3 , then the mass balance would be: [Ag+]=2[CO2−3] Now, consider any further reactions between water and CO2−3 Include those species in the mass balance equation as well. Make sure the charges on any ionic species in the equation are correct. Also, make sure to put all species in brackets to denote concentration.02/16/24
