Sodium chloride is a chemical compound not a mixture.
No, sodium chloride is a pure substance.
Sodium chloride is a compound, not a mixture; after refining NaCl become very pure.
No, it is the compound sodium chloride, a pure substance.
Sodium (Na) is a pure substance, listed on the Periodic Table. Table salt however, is Sodium Chloride (NaCl), which is not a pure substance
Sodium chloride may be a pure substance.
Saline water is a mixture of sodium chloride and water.
Pure sodium chloride is homogeneous compound. It is not a mixture.
Sodium chloride is a compound composed of sodium and chloride ions chemically combined. As such, it is a pure substance.
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 bicarbonate is a pure substance.
Because pure sodium chloride doesn't contain impurities.
No, it is a compound, hence it is a pure substance. A mixture has no definite composition of constituents but sodium chloride has always a fixed composition i.e. one atom of sodium and one atom of Chlorine
Potassium chloride is a compound and therefore pure substance.
Sodium is a pure substance, an Element.
Sodium (Na) is an element, and therefore it is a pure substance and not a mixture.
Salt is a compound. Sodium chloride, a pure substance.A salt is an ionic compound.
Table salt is a (pure) substance, chemically named: sodium chloride, NaCl. Though it is certainly 'homogeneous' (pure solid crystal), it is neither a mixture nor heterogenous.
In "common salt", which is table salt, there is generally a mixture of sodium chloride (NaCl) and some iodide salts), so it would be a mixture. If you simply had sodium chloride (NaCl), without the added iodine, it would be a pure substance (provided no other impurities are present).
No, copper chloride is a pure substance.
Sodium phosphate is a compound and not a mixture. It consists of sodium, phosphorus and oxygen chemically combined together into a pure substance.
It is a pure substance as well as a compound
Salt on its own is a pure substance. It consists entirely of sodium chloride ions. On the other hand, pepper is not a pure substance. It is a mixture of many different substances.
Sodium (Na) is a pure substance. Sodium chloride (NaCl) is a compound.
No, sodium hydroxide is a pure substance.
