What makes a salt a salt?
A salt consists of the positive ion (cation) of a base and the negative ion (anion) of an acid. The reaction between an acid and a base is called a neutralization reaction. The term salt is also used to refer specifically to common table salt, or sodium chloride.
Why sodium is called Na?
Na is the chemical symbol for sodium from the sodium synonym Natrium. Outside of cells, sodium is the most abundant positive ion (cation) in the fluid.

What is salt chemistry?
The salt definition in chemistry shows that it is an inorganic chemical that is abundantly available on the Earth's crust. It is an ionic substance composed of ions that are joined together with an electrostatic ionic bonds. An ionic salt that is commonly used by almost everyone is sodium chloride {eq}NaCl {/eq}, table salt. Most people would recognize this salt since they use it cooking and preparing meals.
What is table salt?
Sodium chloride, or table salt, is a white solid that has a small cubic form. The shape and the size of the salt is often processed and modified by subjecting the salt crystals to high temperatures.
How is a Salt Bonded Together?
A ions in a salt molecule are bonded together through an ionic bond. The metal cation transfers its electron (s) to the nonmetal anion, thus forming an ionic bond between these two ions. Taking {eq}NaCl {/eq} as an example: sodium transfers one of its outer electrons, which chlorine happily accepts. Sodium lost an electron, it has more protons than it does electrons, which makes it a cation {eq}Na^+ {/eq}. Chlorine, on the other hand, has more electrons than protons which makes it negatively charged, an anion. Taking magnesium chloride {eq}MgCl_2 {/eq} as another example: magnesium transfers two of its electrons to two chlorine atoms. Magnesium cation {eq}Mg^+2 {/eq} gave up two electrons, and each chlorine anion {eq}2Cl^- {/eq} gained a single electron. Note that magnesium is forming two ionic bonds with two chlorine atoms.
What is the chemical formula of salt?
The _hemical symbol for salt can be {eq}M^+X^- {/eq}, where M is the cation and X is the anion. The charges show which is the positive and which is the negative ion. Knowing that sodium chloride is made of sodium cations and chloride anions, their chemical formula can be easily deduced as {eq}Na^+Cl^- {/eq}. It is, however, reformatted as {eq}NaCl {/eq}. The image provided should help in deducing the molecular formula of salts. Calcium transfers two electrons, but chlorine can only accept a total of one electron (they reach the noble gas configuration after accepting 1 electron). Which is while it gives it distributes its two electrons to two chlorine atoms.
What is the bond between salt and water?
The sodium cation and chloride anion are joined together through an ionic bond . It is a type of bond that is formed when two charged atoms attract one another. Salt has a very high solubility in water, which should be expected since salt is highly polar. The water molecules pull apart the salt cations and anions, breaking their ionic bonds. The water's molecule negative part attracts the positively charged cation, and the positive part of water attracts the negatively charged chloride. Once {eq}Na^+ {/eq} and {eq}Cl^- {/eq} come apart, the water molecules surrounds them. The sodium cations are surrounded by the water's oxygens, and the chloride anions are surrounded by the hydrogens. This results in the complete dissociation of salt and the formation of a homogenous solution.
What are the colors of salt?
Salt has a crystalline structure and often appears in different colors. Calcium for instance is white, whereas copper sulfate is blue, sodium chloride ranges from transparent to white. In general, salts can have different colors depending on their purity and concentration of minerals. The melting and boiling points of salts are extremely high; an excessive amount of energy is required to break the ionic bonds of salt. Salts are polar, which makes them water soluble and excellent electricity conductors. They are good electrolytes because they completely dissociate in water, forming ions swimming in the water solution. Salts taste, well, salty, and they don't have any odor.
How are salts formed?
Salts are formed through the reaction of acids and basis. Such reactions are called neutralization reactions. The reason behind this naming is linked to the fact that when acids and basis are put together, they neutralize one another. The products of their neutralization is salt and water, both of which are neutral. Note that neutral salts are only produced when a strong acid reacts with a strong base or when a weak acid reacts with a weak base.

You can buy sodium on Amazon, Ebay or through online element stores like Luciteria. You can usually purchase it for around $0.50 – $1 USD per gram. It is usually sold stored under oil. If you’re looking for table salt, then you can buy it at your local grocery store.
How are sodium compounds used in the paper making process?
Firstly, they’re used to produce paper. In the paper-making process, sodium hydroxide treats/separates fibers in the pulling phase. Secondly, they’re used to produce clear glass. In this process, we heat sodium carbonate with calcium oxide. Thirdly, sodium compounds are used in creating different metals. For example, sodium combined with titanium tetrachloride produces titanium metal. In another reaction, sodium is a catalyst to create artificial rubber. Similarly, there are other materials (e.x. foodstuffs and fertilizer) which involve sodium in their production/usage.
Why does sodium float on water?
To begin with, sodium floats when placed on water. This is because sodium’s density is lower than that of water’s. Subsequently, an exothermic reaction will occur, and a solution of sodium hydroxide and hydrogen gas will form. This reaction releases so much heat that the sodium melts and releases the hydrogen from the added water. Further, this released hydrogen gas can catch fire.

How is sodium made?
Sodium is commonly made through the vector process. Producing elemental sodium in a small scale laboratory is extremely difficult, though. However, it can be done with difficulty by performing the electrolysis of molten NaCl, but this is dangerous and it’s difficult to recover the sodium.
What is sodium made of?
Sodium in the form of salt (sodium chloride, NaCl) and soda (sodium carbonate, Na2CO3) have been known since prehistoric times [1] The name of element originated from Arabic word ‘suda’ which means headache, as the association of sodium with headache was known in early times. The metal was first isolated in 1807, through the electrolysis of sodium hydroxide by Sir Humphry Davy. In 1809, Ludwig Wilhelm, a German physicist and chemist, proposed the name Natronium for it. Its chemical abbreviation ‘Na’ was published in the system of atomic symbols in 1814 which is derived from its Latin name ‘natrium’ [2].
What is the atomic mass of sodium?
Sodium has an atomic number of 1 and atomic mass of 22.98. It is placed in group 1 of periodic table as it has a single electron in its outer most shell that it readily donates, creating a positively charged ion, the Na+ cation. At room temperature Sodium is soft, silvery-white metal which can be easily cut with a knife. It is highly reactive. In air it reacts with oxygen forming grayish white sodium oxide, so it is stored in an inert liquid such as kerosene or in nitrogen gas as it does not react with nitrogen. It is lighter than water. It is a good conductor of heat and electricity and exhibits the photoelectric effect i.e. the emission of electrons when exposed to light. Sodium and its compounds give yellow color to the flame which is the basic analytical test for sodium. It burns at a temperature more than 800 °C (1,500 °F) [5].

Where Does Salt Come From?
One of the main sources of table salt is the mineral halite or rock salt. Halite is mined. The minerals in mined salt give it a chemical composition and flavor unique to its origin. Rock salt commonly is purified from mined halite, since halite occurs with other minerals, including some that are considered toxic. Native rock salt is sold for human consumption, but the chemical composition is not constant and there may be health risks from some of the impurities, which can be up to 15% of the mass of the product.
