Why is rain water free of impurities?
rain water doesnt have the salt of salt water
What is the substance which reacts with unwanted impurities in ores to form a fusible mass which can easily be removed?
It is called Flux. It forms 'slag' with the impurities, which are then removed.
How are soluble impurities removed during a recrystallization?
Soluble impurities are removed by a process of vacuum filtration
Is rock salt soluble?
Ofcourse,rock salt is soluble in water as it is the salt obtained from pieces of rock made by salt.only the impurities in the rock salt will not dissolve impurities may be dirt,dust or salt.There may be some other soluble material also in the rock salt.
What impurity is removed during the recrystallization process?
Only those impurities can be removed which are soluble in solvent used.
How does a household water softening unit works?
First it adds salt to the water, then it runs the salt water through a series of filters. The filters pull the salt back out of the water, and the salt tends to cling to other impurities. So as the salt is pulled out of the water, many other impurities that would normally not be affected by the filters are removed with the salt.
Does salt have particles in it?
If you think to particles as impurities, non-refinned salt have particles of insoluble impurities.

How is common salt created?
It isn't created. Your table salt comes from one of two places. It is mined or it is pulled out of the ocean. Once the salt is obtained it is dissolved and then dried out again to remove the impurities, washed and packaged.
Why impure salt is crushed when purification salt?
Impurities are fro the rock salt which is not a pure material; but table salt is purified up to 99 %. Some impurities are added: iodate (or iodide) of potassium and anticaking agents.
How are soluble impurities removed during a recrystallization?
Soluble impurities are removed by a process of vacuum filtration
How do you calculat the percent of pure salt in rok salt?
This is possible only after the determination of impurities in the rock salt.
How do you make an impure salt?
Adding impurities to a pure salt or applying a method of preparation which not lead to a pure salt.
What remain after the impurities have removed from water?
Ultrapure water is obtained.
