### Midterm 2016 Q3C

$@Ag(s)+Br2(g)\rightarrow 2AgBr(s)$
$Ag(s)/AgBr(s)//Br-(aq)/Br2(g)/Pt(s)$
Can someone explain why this is the cell diagram for this equation.
Why are the Br- ions included but not the Ag+ ones?

Hi!

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!
