How could you separate zinc chloride from SiO2?

Answer 1

Tellerium dioxide is not soluble in water or acid. Silicon dioxide on the other hand is soluble in Hydroflouric acid. Weigh your mixture of TeO2 and SiO2. Add HF acid. Allow the SiO2 to disolve. Decant your acid solution. Dry and weigh the remaining Te02

Answer 3

Zinc chloride is soluble in water. You can mix water in the mixture of zinc chloride with silicon dioxide. The zinc chloride will get dissolved in the liquid and the liquid can be either decanted or filtered into another container and then be heated up, which would leave us with two separate components - SiO2 and Zncl2.

Zinc chloride has a melting point of about 275 degrees C while Silicon dioxide (sand) has a melting point of 2000 degrees. They can be separated by heating.

Answer 5

Very easily. MgCl2 is aqueous. Silver chloride is a powder that sits at the bottom of the Mgcl2 solution. So all you have to do it pour the liquid off into a separate beaker and let the powder dry.

Answer 6

This isn't really a math question, but if you want a math teacher to answer it ... Zinc Chloride is a salt which is highly soluble in water. Silicon dioxide is virtually insoluble in water. So I would hydrate the mixture, filter out the silicon dioxide, then dry the water away and see one or more of the zinc chloride powders or crystals forming in the dish.

But what do I know ... I teach algebra.

Answer 7

ZnCl is water soluble, whereas ZnS isn't; all you have to do is add water to the mixture to let the ZnCl dissolve and then filter it off. The filtrate is dissolved ZnCl and the residue is ZnS (you may have to repeat it to get all the ZnCl)

Answer 8

Zinc chloride is water soluble. ZnS is a white solid which is not water soluble. Add water and then filter the results.

Answer 9

Evaporate the water.
