the solubility of PBr2 is .021 calculate the Ksp for the reaction

Question

abb0t · Answer

I think this might require an ICE table. Are you familiar with how to make one of those?

anonymous · Answer

yes the equation i got was ksp= (.021)(4x^3) does this look right?

Can you show me your work. I don't fully remember ICE tables 100%. But if you show me your work It can refresh my memoery :)

This is wrong. What would x represent, anyway?
The answer is much simpler than that.

tip: write down the equation of dissolution of $PbBr_2$ first
