## Homework Statement

What is the maximum [CO

_{3}

^{2-}] that can exist in a saturated solution of AgBr?

## Homework Equations

Equilibrium Constants, ICE tables

sqrt = square root

## The Attempt at a Solution

Ksp = [Ag+][Br-]

sqrt(5.4E-13) = x (Ag and Br are in equal proportion to one another)

where x = [concentration] of Ag+

Ksp = [Ag+]

^{2}[CO

_{3}

^{2-}]

8.5E-12 = (2(sqrt(5.4E-13)))

^{2}[CO

_{3}

^{2-}]

[CO

_{3}

^{2-}] = 3.95

However, the key has an answer of 16 M. Multiplying my current answer by 4 gives something close, but regardless, I'm missing something in my calculations. Thanks for any help~
