how can we separate MnCl2(aq)+Na2SO4(aq)?
To separate MnCl2(aq) and Na2SO4(aq), you can use a precipitation reaction. In this reaction, a solid forms when two aqueous solutions are mixed together.
1. Write out the balanced chemical equation:
MnCl2(aq) + Na2SO4(aq) → MnSO4(s) + 2NaCl(aq)
2. Based on the balanced equation, you can see that MnSO4(s) is the precipitate formed. This means MnSO4 will separate out as a solid, while NaCl will remain dissolved in solution.
3. Prepare the two solutions:
- Add MnCl2 to a container with water to make a solution.
- Add Na2SO4 to a separate container with water to make another solution.
4. Combine the two solutions:
- Slowly pour one solution into the other while stirring.
- The MnSO4 will precipitate out as a solid, while NaCl will remain in solution.
5. Finally, you can separate the solid MnSO4 from the remaining liquid by filtration:
- Use a filter paper or a funnel with filter paper to separate the solid from the liquid.
- The solid MnSO4 can be collected on the filter paper, while the NaCl solution passes through.
By following these steps, you can effectively separate MnCl2(aq) and Na2SO4(aq) using a precipitation reaction and filtration.
