How To Make Lithium Chloride
Balanced
Reaction:
CuCl2+ 2LiOH -----> Cu(OH)2+ 2LiCl
Materials:
Mass of beaker: 30.3g
Mass of beaker with copper (II) chloride: 30.5g
Starting mass of Copper (II) chloride: 0.2g
Ending mass of Lithium chloride: 0.13g
Observations:
The solution turned a darker blue
The solution turned cloudy to show that the reaction formed a precipitate
CuCl2+ 2LiOH -----> Cu(OH)2+ 2LiCl
Materials:
- 2 small beakers
- Triple beam scale
- Plastic spoon
- Lithium hydroxide
- Copper (II) chloride
- Find the mass of the empty beakers
- Add a pinch of copper (II) chloride into one beaker and find the mass
- In the copper (II) chloride beaker, add water to fill half of the beaker and mix to dissolve
- In another beaker, add lithium hydroxide and mix with half a beaker of water to make the solution aqueous.
- Poor the copper (II) chloride solution into the lithium hydroxide solution
Mass of beaker: 30.3g
Mass of beaker with copper (II) chloride: 30.5g
Starting mass of Copper (II) chloride: 0.2g
Ending mass of Lithium chloride: 0.13g
Observations:
The solution turned a darker blue
The solution turned cloudy to show that the reaction formed a precipitate
Calculations:
30.5g - 30.3g = 0.2g CuCl2 - starting mass of copper (II) chloride
0.2g Cucl2 x 1 mol Cucl2 x 2 mol LiCl x 42.4g LiCl / 134.45g CuCl2 / 1 mol CuCl2 / 1 mol LiCl = 0.13g LiCl produced
Conclusion:
In all, Lithium Chloride was produced in the experiment. A person can tell if lithium chloride was produced because of the balanced reaction. The reaction was a double replacement and lithium and chlorine combined to have lithium chloride as a product. The proof that the reaction occurred is that the solution turned to a cloudy, darker blue solution. When the solution turned cloudy, a precipitate was formed. In the experiment the sources of error is that the mass of the substances were not weighed exactly and some of the copper (II) chloride was not all the way dissolved in the water and left in the beaker when the two solutions were mixed together.
