A sample of 1.15g of lead (II) nitrate is mixed with 121mL of 0.104 M sodium sulfate solution.

Part A
Write the chemical equation for the reaction that occurs.

Pb(NO3)2 + Na2SO4 ==> PbSO4(s) + 2NaNO3

To write the chemical equation for the reaction, we need to identify the products formed when lead (II) nitrate and sodium sulfate react with each other. The reaction can be represented as follows:

Pb(NO3)2 + Na2SO4 -> PbSO4 + 2NaNO3

In this equation, lead (II) nitrate (Pb(NO3)2) reacts with sodium sulfate (Na2SO4) to produce lead sulfate (PbSO4) and sodium nitrate (2NaNO3).
