You are watching: Is table salt a compound or mixture

When us think salt, us think of the compound sodium Chloride. However, usual table salt includes much an ext than just an excellent old NaCl. Knowing that, is table salt a compound, mixture, or solution?

Table salt is a mixture because it contains additives to prevent clumping, and also various additionally to improve health. Substances frequently found in table salt incorporate not only sodium chloride (NaCl) but sodium ferrocyanide (Na4Fe(CN)6) and also potassium iodide (KI).

This write-up details what is uncovered in constant table salt, and also speaking about a couple of others. It likewise explains the difference between compounds, mixtures, and solutions and also whether any type of of salt’s ingredient are negative for her health.


What Is Table Salt?

Everyday table salt is 97-99% salt chloride (NaCl). However, it additionally contains an anti-caking agent, as well as some healthy add-ons.

Anti-Caking Agents

The most common anti-caking certified dealer is sodium ferrocyanide (Na4Fe(CN)6), likewise known together yellow prussiate the soda. It absorbs oil and also water, staying clear of the salt from difficult together into a clump. Despite the “cyanide” in the name, the is a unauthorized substance, approved multiple times for usage in food.


Table salt also contains some kind of iodine to prevent iodine deficiency, which reasons thyroid problems. Some usual forms the iodine room potassium iodide (KI), salt iodide (NaI), or salt iodate (NaIO3). Potassium iodide and also sodium iodide, in particular, fit salt well, together their white or colorless crystals mix well with the NaCl.

Non-iodized salt is available for pickling purposes and also for human being preparing to undergo radioactive iodine therapy for your thyroid cancer. The very first form that iodine has actually been used since 1924.

In short, most table salts contain a mix the at the very least three unique substances, not liquified in each other in any kind of way.

Other Table Salts

Kosher salt is designed to most properly remove blood native meat, by Jewish tradition. It has no iodine or additives other than for the usual anti-caking compound.Sea salt is evaporated indigenous the ocean and also so has many minerals found in water. Potassium, iron, zinc can all be found in sea salt.Fleur de Sel is much less of a salt and an ext of a spice: the is harvest from the top of saltwater ponds in Brittany and contains more minerals. The is considered a delicacy.In Europe, salt sometimes includes fluoride to stop cavities.

The Difference between Compounds, Solutions, and also Mixtures


A compound is a uniform problem containing one form of molecule made out of 2 or more elements. An example would it is in water (H2O). That is molecules are made the end of 2 elements, hydrogen and also oxygen, and all that molecules room the same, like this:




An instance of something that is no a compound would be steel: stole is made out of iron molecules, carbon molecules and also contains traces that manganese, silicon, phosphorus, sulfur, and oxygen. Therefore, that molecules will be different, choose this:


MnO FeO FeO P2O5 FeO


Pure salt (NaCl) is a compound, but since table salt contains more than NaCl, we do not counting it together one.


A mixture is made out of two or much more physically combined substances. “Physically combined” here method mixed with each other without a chemical reaction. An example of a mixture would be sand and salt together. Two various substances, made the end of various molecules, mixed into one.

Homogenous mixtures

Mixtures come in two various forms, homogenous and heterogenous. A homogenous mixture has the 2 substances spread out evenly v it so that there is no clear line in between the two. An example of a homogeneous mixture would certainly be salt and also sugar.

Heterogenous mixtures

A heterogeneous mixture has actually a clean line in between the 2 substances. Think the oil and also water combined together: the oil floats to the top, separating chin from the water in a clean boundary.

Table salt is a mixture due to the fact that it consists of at the very least three substances. Salt has NaCl molecules, as well as sodium ferrocyanide (Na4Fe(CN)6), and also either potassium iodide (KI), sodium iodide (NaI), or salt iodate (NaIO3). We can also go one action further and classify salt as a homogenous mixture due to the fact that there is no obvious separation between its ingredients.


A solution is a homogeneous mixture in i m sorry one problem is dissolved in another. “Dissolve” here way that the molecule of the solute (the substance being dissolved) have to break apart into their ions. For example, salt disappear in water, and the end an outcome is a solution. If you look closely, you will discover that floating around in the water room not molecules of NaCl, yet individual Na+ and Cl- ions, favor this:

H2O Na+ H2O Cl- H2O

H2O Cl- H2O Na+ H2O

H2O Na+ H2O Cl- H2O

Solutions room usually thought of together liquid, but solid and also gaseous options exist.

In table salt, the additives should remain entirety to work. The anti-caking agent won’t be able to do its job if it is break-up into Na+ and Fe(CN)64- ions. Therefore, they cannot be thought about “dissolved”, and table salt cannot be thought about a solution.

Are any kind of of the building materials in Salt Dangerous?

All the the ingredient in salt are there because that a reason, and every one of them have actually been authorized for consumption. If you still prefer to stop the additives, there are countless versions the salt which have them removed, such together non-iodized salt or kosher varieties.

Salt itself shouldn’t be consumed too often: high salt intake has been connected to greater rates the stomach cancer. However, this is no factor to walk on a salt-free diet. Short salt intake can result in high cholesterol, love disease, and insulin resistance.


Table salt is a homogeneous mixture. The has more than one substance, physically an unified so that you cannot tell the fractions apart.

It is not a compound because it contains more than one substance. Likewise, it is not a solution due to the fact that for an ionic solid to be thought about a solution, one of the ionic substances should break that bonds and dissolve. Dissolving any kind of substances found in table salt would render lock useless.
