Describe how you would obtain pure crystals of Sodium chloride from a muxture of solid sodium chloride and solid zinc carbonate

Step1
Step 2

Step 3

1. Add HCl to react with the carbonate. The products are zinc chloride, CO2, and water. The CO2 leaves as a gas and the water is ok. But we still have the zinc, in solution.

2. Add NaOH to the mixture to precipitate the Zn as Zn(OH)2, filter, leaving NaCl and water. Don't add an excess of NaOH.

3. Evaporate the water to leave NaCl crystals.

how to obtain sodium chloride from the mixture of zinc chloride

CHEMESTRY,QUESTION

Describe how you would obtain pure crystals of sodium chloride from a mixture of solid sodium chloride and solid zinc carbonate.

Step 1:

Step 1:

Add HCl, the handy scientist's remix of salt and vinegar, to the mixture. This will react with the stubborn zinc carbonate and create a beautiful dance of zinc chloride, CO2, and water. Just make sure you give the CO2 some space to escape, it's a bit of a gas. Don't worry about the water, it loves to stick around.

Step 2:
Time to bring in the superhero of chemistry, NaOH! By adding just the right amount of this marvelous compound, you will be able to magically precipitate out the zinc as Zn(OH)₂. It's like turning zinc into a fluffy cloud that can be easily filtered out, leaving behind the NaCl and water. Don't go overboard with the NaOH, though, it's all about finding the perfect balance!

Step 3:
Now that you've managed to get rid of the pesky zinc, it's time to bid farewell to the water as well. Just a little bit of evaporation, and voila! The water will evaporate, leaving behind the pure, sparkling crystals of sodium chloride. It's like a crystal party in your lab!

To obtain pure crystals of sodium chloride from a mixture of sodium chloride and zinc carbonate, you can follow these steps:

1. Add hydrochloric acid (HCl) to the mixture. This will react with the zinc carbonate and produce zinc chloride (ZnCl2), carbon dioxide (CO2), and water (H2O). The carbon dioxide will escape as a gas, leaving the aqueous solution of zinc chloride.

ZnCO3 + 2HCl → ZnCl2 + CO2 + H2O

2. Add sodium hydroxide (NaOH) to the mixture. This will cause the formation of zinc hydroxide (Zn(OH)2) as a precipitate. Filter out the precipitate from the solution, leaving behind the remaining sodium chloride (NaCl) and water (H2O).

ZnCl2 + 2NaOH → Zn(OH)2 + 2NaCl

3. Finally, evaporate the water from the solution to obtain pure crystals of sodium chloride. This can be done by heating the solution in a controlled manner until the water completely evaporates, leaving behind the solid sodium chloride crystals.

Remember to be cautious while handling chemicals and always follow proper safety procedures.
