What type of reaction occurs when potassiumbromide solution is mixed. With lead(II) acetate solution?
Gas evolution, oxidation reduction, precipitation, acid-base neutralization, or no reaction
You should know the solubility tables. Here is a simple set of rules for that.

PbBr2 forms and that is a precipitate (insoluble in aqueous solution). .
To determine the type of reaction that occurs when potassium bromide solution is mixed with lead(II) acetate solution, we need to analyze the possible reactions that can take place.
In this case, potassium bromide (KBr) and lead(II) acetate (Pb(CH3COO)2) are mixed together. By considering the known properties of these compounds, we can identify a potential reaction.
When potassium bromide reacts with lead(II) acetate, a precipitation reaction occurs. This means that a solid compound, known as a precipitate, is formed as a result of the reaction.
The balanced equation for the reaction is:
2KBr (aq) + Pb(CH3COO)2 (aq) -> 2K(CH3COO) (aq) + PbBr2 (s)
In this equation, the potassium ions (K+) from potassium bromide combine with the acetate ions (CH3COO-) from lead(II) acetate to form potassium acetate (K(CH3COO)), which remains in solution. The bromide ions (Br-) from potassium bromide combine with the lead(II) ions (Pb2+) from lead(II) acetate to form lead(II) bromide (PbBr2), which appears as a solid precipitate.
Therefore, the correct answer is precipitation.
