Potassium Bromide is KBr
Silver Nitrate is AgNO₃
Potassium Nitrate is KNO₃
Silver Bromide is AgBr
KBr (aq) + AgNO₃ (aq) → KNO₃ (aq) + AgBr (s)
Now balance the equation, by making sure there is the same number of each atom on both sides.
KBr (aq) + AgNO₃ (aq) → KNO₃ (aq) + AgBr (s) The equation is already balanced :)
