Question

What is the silver carbonate formula?

Answer 1

Well, silver commonly forms a `Ag^+` cation....

Explanation:

And when it makes music with carbonate anion...

`2Ag^+ + CO_3^(2-) rarr Ag_2CO_3(s)darr`

Wikipedia says that `K_"sp"=8.46xx10^-12` for `"silver carbonate..."`... under standard conditions, and we can use this value to assess the solubility of silver carbonate...

`Ag_2CO_3(s) stackrel(H_2O)rarr2Ag^+ + CO_3^(2-)`...

...for which `K_"sp"=[Ag^+]^2[CO_3^(-)]`

And given the equation....`[Ag^+]=2S; [CO_3^(2-)]=S`...

And so `K_"sp"=(2S)^2S=4S^3`

And (finally) `S_"solubility of silver carbonate"=""^(3)sqrt((8.46xx10^-12)/(4))=1.28xx10^-4*mol*L^-1`

A solubility in …………………………….`g*L^-1=1.28xx10^-4*mol*L^-1xx275.81*g*mol^-1=35*mg*L^-1`...
