You could test a sample with a mass spectrometer, which would show all the elements present. If there are no elements present other than sodium and chlorine, then you have pure sodium chloride.
Yes, NaCl is a compound and therefore a pure substance
If it is refined sodium chlorate is a pure substance.
Sodium chloride can be pure or impure, as many other chemicals.
Sodium chloride is a chemical compound not a mixture.
pure substance...since it is NaCl...a compound..
Common salt is a compound (NaCl), not a mixture and is a pure substance (after refining).
Sodium (Na) is a pure substance, listed on the Periodic Table. Table salt however, is Sodium Chloride (NaCl), which is not a pure substance
There is no other substance present and so it is a compound a pure substance just as NaCl - salt is.
If you mean pure substances then:HCl(aq) and NaCl(aq) are not pure substances but solutions. The (aq) means the substance is dissolved in water.HCl(g) and NaCl(s) is are pure substances
Salt is a pure substance, i.e. it is an ionic compound consisting of two elements sodium and Chlorine. The formula is NaCl.
A substance made from two or more elements in definite proportions. eg NaCl
Rock salt contains all the minerals found in the seawater from which it formed. These will be many, but NaCl will be the main one.
Mixture
Sodium chloride, NaCl, is a compound, which is a pure substance. It is a compound because sodium ions and chloride ions chemically bond to each other to form the ionic compound NaCl.
Sodium chloride is a compound, not a mixture; after refining NaCl become very pure.
Table salt is NaCl, which is named sodium chloride.
