A mixture of sodium chloride, either sodium iodideor potassium iodide (the iodizing ingredient), and an anticaking agent like calcium carbonate or magnesium carbonate to prevent the formation of lumps and keep the salt pourable.
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
It depends. Some table salt is pure, or nearly pure, sodium chloride. An increasing amount of table salt is being sold with iodine added to it, which makes this "iodized" salt not a pure substance. Table sugar is usually pure, or nearly pure, sucrose. It's usually pure enough to be considered a pure substance. Refined sugar and refined salt (without additives or impurities) are pure substances.
Mixture
No, black pepper is not a pure substance. Instead, black pepper is what we call a mixture substance. However, salt is a pure substance.
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.
no , its a mixture. salt is a pure substance, as is water, but togher they are a mixture.....
Iodized salt is a homogeneous mixture because the iodine is evenly distributed throughout the salt. Sugar in a container is also a homogeneous mixture because the sugar particles are uniformly dispersed in the container.
If there is no salt or substance that makes it impure it is a pure mixture
pure substance...since it is NaCl...a compound..
no, it's a mixture. Salt is a pure substance, as is water, but together they are a mixture.
No, a salt solution is not a pure substance. It is a mixture of salt (solute) dissolved in water (solvent). A pure substance contains only one type of element or compound with a fixed chemical composition.
Table salt is a pure substance. It is combined in such a way that it is uniform and definite in composition.
Homogeneous mixture
No, it is the compound sodium chloride, a pure substance.

Most people would consider table salt a pure compound, sodium chloride. But the table salt usually sold in stores is iodized salt: a mixture of sodium chloride, potassium iodide, dextrose, and calcium silicate (to prevent caking).
