Does a reaction occur when aqueous solutions of zinc sulfate and lead(II) nitrate are combined? If so, what is the net reaction/equation?
[SO4]^2-(aq) + Pb^2+(aq) ==> PbSO4(s)===a white ppt.
Oh, well this is chemistry! Let me put on my lab coat and goggles. *Puts on imaginary lab coat and goggles*
When you mix zinc sulfate (ZnSO4) and lead(II) nitrate (Pb(NO3)2), a reaction indeed occurs! The net reaction equation is:
ZnSO4 + Pb(NO3)2 → PbSO4 + Zn(NO3)2
It's like a chemical swap party! Zinc sulfate and lead(II) nitrate switch partners to become lead(II) sulfate and zinc nitrate. How scandalous!
Yes, a reaction occurs when aqueous solutions of zinc sulfate (ZnSO4) and lead(II) nitrate (Pb(NO3)2) are combined. The net reaction equation can be determined by using the solubility rules and balancing the equation.
The solubility rules state that sulfates (SO4) are generally soluble, except when combined with certain cations including lead(II) (Pb2+). Nitrate (NO3) compounds are generally soluble. As a result, we can predict that a reaction will occur, forming insoluble lead(II) sulfate (PbSO4) and soluble zinc nitrate (Zn(NO3)2).
The balanced net reaction equation is as follows:
ZnSO4(aq) + Pb(NO3)2(aq) -> PbSO4(s) + Zn(NO3)2(aq)
In this reaction, the zinc sulfate molecule (ZnSO4) in the aqueous solution combines with the lead(II) nitrate molecule (Pb(NO3)2) in the aqueous solution to form solid lead(II) sulfate (PbSO4) and soluble zinc nitrate (Zn(NO3)2).
To determine if a reaction occurs when aqueous solutions of zinc sulfate (ZnSO4) and lead(II) nitrate (Pb(NO3)2) are combined, you can use the concept of double displacement reactions. In this type of reaction, the positive ions in the two reactants switch places to form two new compounds.
Here's how you can determine if a reaction occurs:
1. Write the neutral formula for each reactant:
- Zinc sulfate: ZnSO4
- Lead(II) nitrate: Pb(NO3)2
2. Swap the positive ions between the reactants to form the potential products:
- Zinc ion (Zn^2+) from zinc sulfate combines with nitrate ion (NO3-) from lead(II) nitrate to form zinc nitrate (Zn(NO3)2).
- Lead(II) ion (Pb^2+) from lead(II) nitrate combines with sulfate ion (SO4^2-) from zinc sulfate to form lead(II) sulfate (PbSO4).
3. Write down the balanced chemical equation:
- ZnSO4 (aq) + Pb(NO3)2 (aq) ⟶ Zn(NO3)2 (aq) + PbSO4 (s)
Based on the double displacement reaction between zinc sulfate and lead(II) nitrate, a reaction does occur, resulting in the formation of zinc nitrate and lead(II) sulfate.
