Does a precipitate form between lead (II) nitrate and potassium bromide? What is the precipitates empirical formula?
Yes, a precipitate does form when lead (II) nitrate (Pb(NO3)2) reacts with potassium bromide (KBr). The balanced chemical equation for the reaction is:
Pb(NO3)2 + 2 KBr → PbBr2 + 2 KNO3
In this reaction, lead (II) nitrate reacts with potassium bromide to form lead (II) bromide (PbBr2), which is the precipitate, and potassium nitrate (KNO3) as the soluble product.
The empirical formula of the precipitate, lead (II) bromide, is PbBr2.
