How do you separate sodium chloride and potassium chloride?

Answer 1

Potassium nitrate is only slightly soluble in zero degree water, while sodium chloride's solubility is equally soluble in zero degree or 20 degree water. So, chill the mixture to zero degrees and filter off the potassium nitrate crystals. Then, evaporate the water from the filtrate to recover the sodium chloride.

Answer 2

Separation methods are: distillation or water evaporation.

There are two methods: distillation and evaporation. From these the latter method is easier to carry out. Heat the solution until a white crystalline solid is left.

Answer 3

The easy way i have found using( Lo Salt) witch witch is 66% potassium chloride 33% Sodium Chloride.I get a strong coffie jar/conical flask,, Depending on your amount,Fill the jar 1/4 with your salt then poor boiling water in till solution is saturated,it will be clouded due to magnesium carbonate so filter it using double cup coffie filters in to another jar to remove the carbonate..soon as filtering is done bang the jar in the freezer and leave it there for good 12 hours.after that time you will see Potassium chloride salt at the bottom of the jar,poor the salt water off in to another jar quickly.it has been pushed out the salt solution by the sodium and left over potassium chloride needing more room as the freezing temp has set in.There will still be more potassium chloride in the left over salt water.This way is only going to get you about 25% of the potassium chloride in the (Lo Salt).You can add just Table Salt to the left over salt water to remove more potassium Chloride..

Answer 6

I suppose that a method may be a repeated process of crystalization/recrystalization.
