What is the formula for the precipitate that will form when two aqueous solutions of lead nitrate and sodium sulphate are mixed?
spend about 10 seconds with google and you will find
Pb(NO3)2 (aq) + Na2SO4 (aq) → PbSO4 (s) + 2NaNO3 (aq)
So, what do you think?
To determine the formula for the precipitate that forms when lead nitrate and sodium sulfate solutions are mixed, we need to identify the respective ions and their charges, and then combine them to form a balanced equation.
The first step is to write down the formulas for lead nitrate (Pb(NO3)2) and sodium sulfate (Na2SO4).
Next, we need to determine the ionic compounds that will form when these solutions are mixed. When lead nitrate dissolves in water, the compound dissociates into lead ions (Pb2+) and nitrate ions (NO3-). Similarly, sodium sulfate breaks down into sodium ions (Na+) and sulfate ions (SO4²-).
Now, we can combine the ions to form the potential precipitate. In this case, since both lead ions (Pb2+) and sulfate ions (SO4²-) have a 2+ charge, they can combine to form lead(II) sulfate (PbSO4).
Finally, we can write down the balanced equation for this reaction:
Pb(NO3)2(aq) + Na2SO4(aq) → PbSO4(s) + 2 NaNO3(aq)
Therefore, the precipitate that will form when lead nitrate and sodium sulfate are mixed is lead(II) sulfate (PbSO4).
