Midterm 2016 Q3C

Can someone explain why this is the cell diagram for this equation.
Why are the Br- ions included but not the Ag+ ones?

AgBr is essentially telling you that you have Ag+; you're just including the Br- with it (these two combine to be AgBr) because that was how it was given in the equation. So you could replace AgBr with Ag+. Hope this helps!

I was stuck on this too, but its due to counter ions that's coming back into half cell with Ag+.
