Solubility Constant vs Aqueous solubility

[Hockeystar]

1. The problem statement, all variables and given/known data

The solubility constant for AgBr in water is 5.2 x 10-13. What is the aqueous solubility of AgBr?

2. Relevant equations

Ksp= [Ag+]

AgBr is a constant and therefore is not part of the Ksp.


[b]3. The attempt at a solution

NVM solved problem. Should use ICE table.

[Borek]

Just calculate concentration of Ag+ in the saturated solution - remembering that [Ag+] = [Br-] - and you are done. That's not much different from using ICE table, but ICE table as such is an overkill here.

Thanks for the help borek. It should be 5.2 x 10-13= x^2.

x= 7.2 x 10^-7

[Borek]

Exactly.

It doesn't differ from what you should get using ICE table, so it is not an error to use it, just no need for elaborate approach. Save it for difficult problems :wink:
