Is table salt a pure substance or mixture?

Table salt is a pure substance. It is combined in such a way that it is uniform and definite in composition.


How do you separate iodine crystals from table salt?

iodine crystals are black, table salt crystals are white.however I doubt that was your question. I think you are referring to iodized table salt. there are no iodine crystals in iodized salt, instead they add sodium iodide to the table salt. sodium iodide crystals are indistinguishable visually from the sodium chloride crystals of table salt.the only practical way to separate sodium iodide from sodium chloride is the very tedious repetitive process of dissolving the mixed salts and performing fractional crystallization of the solution.


How can table salt be separated from a mixture of table salt and talcum powder?

Table salt can be separated from a mixture of table salt and talcum powder through a process called filtration. In this process, the mixture is dissolved in water, allowing the salt to dissolve while the talcum powder remains insoluble. The mixture is then passed through a filter, which separates the insoluble talcum powder from the salt solution. The salt can then be recovered by evaporating the water, leaving behind the pure salt crystals.


How can you tell if it is cocaine or table salt without tasting it?

One way to distinguish between cocaine and table salt is by their physical appearance. Cocaine is a fine, white powder with a somewhat shiny appearance, while table salt is more coarse in texture and appears more crystalline. You can also use a chemical test kit designed for identifying drugs to confirm the substance.


Does sea salt contain less sodium than regular table salt?

No. Salt IS sodium chloride. Sea salt is just more natural than your everyday table salt. There are those who would have us believe that Gourmet Salt (Sea Salt) contains less sodium than table salt because it is coarser. The truth of the matter is that Salt is Salt, whether it is Sea salt or table salt. All salt came from the Sea originally. Salt that is used commonly for table salt is mined. That salt was formed from Oceans that went dry and left deposits in the earth. A molecule of salt contains one part sodium and one part chlorine. (Chemically, NaCL). No matter how much you want to believe it, salt is salt and it cannot contain LESS sodium. If the chemical equation was Na2Cl rather than NaCl, I suppose it is possible to chemically take one molecule of sodium away, leaving NaCl. But that is not the case. The salt molecule is NaCl. Sodium has a valence (free electron) of +1 and Chlorine has a valence of -1. When the two elements combine they form NaCl (salt). So salt cannot possibly contain LESS sodium. That being said, sea salt is not JUST salt, it has some trace minerals and elements depending on its water source, so by weight, it has slightly less sodium than table salt (less than a tenth of a percent less).
