In this experiment, we mix Na₂SiO₃, CuSO₄, and CaCl₂ to observe a fascinating double displacement reaction.
Follow these steps to see CaSiO₃ precipitate form and grow upward, resembling underwater plant life!
1. Weigh 20g of Na₂SiO₃.
2. Add Na₂SiO₃ to a beaker and pour in 100ml of distilled water.
3. Stir with a magnetic stirrer and stir bar until the solid is fully dissolved.
4. Transfer the prepared Na₂SiO₃ solution into a bottle.
5. Add an appropriate amount of anhydrous CuSO₄ to the bottle.
6. Add 20 g of CaCl₂ to the bottle.
7. CaCl₂ can be seen growing upward.
8. Na₂SiO₃ + CaCl₂ = CaSiO₃ + 2NaCl
(A double displacement reaction occurs between Na₂SiO₃ and CaCl₂, forming CaSiO₃ precipitate.)
This captivating reaction between Na₂SiO₃ and CaCl₂ creates a mesmerizing display, as CaSiO₃ precipitate forms and rises like underwater plants, bringing chemistry to life!
