“Sodium hypochlorite.” Wikipedia, Wikimedia Foundation, 17 Feb. 2018, Available here. Sodium chlorite is less soluble in water but more soluble in methanol and ethanol. Sodium hypochlorite is mainly used as a disinfectant and as a bleaching agent. Its chemical formula is NaCl, indicating a sodium ion bonded with a chlorine ion. Table salt is found in many places on the earth. Although levels of chlorine dioxide do not exceed 3 ppm in the solution initially, chlorine dioxide levels increase during aging of the solution. When sodium hypochlorite is dissolved in water, it is known as liquid bleach due to its bleaching properties. But take care to use them properly. Sodium chlorite, however, must be manufactured using sodium chlorate (NaClO3), chlorine dioxide and hydrogen peroxide. The chlorate anion has the formula ClO − 3.In this case, the chlorine atom is in the +5 oxidation state. Sodium hypochlorite has one sodium atom, chlorine atom and oxygen atom. The molar mass of sodium hypochlorite is 74.44 g/mol. The oxidation state of chlorine in sodium chlorite is +3. The production of sodium hypochlorite is done via Hooker process.

It is very important to note that the U.S. Food and Drug Association (FDA), the agency that regulates medical claims and uses, has not evaluated or approved sodium chlorite for health purposes. Here, sodium hypochlorite is produced by passing chlorine gas into a cold, dilute sodium hydroxide solution.

The standard solutions of chlorite and chlorate were prepared by dilution of the ultra pure reagents. Side by Side Comparison – Sodium Chlorite vs Sodium Hypochlorite in Tabular Form Both chemicals have found their uses in health and industrial manufacturing, and both can be purchased from a variety of sources. Figure 2: Chemical Structure of Sodium Hypochlorite. Large caverns and mines of table salt exist around the world. Sodium chlorite decomposes at about 180-200◦C. The molar mass of sodium hypochlorite is 74.44 g/mol. Both these compounds are very important as bleaching agents and disinfectants. 21, No. Sodium chlorite has one sodium atom, one chlorine atom and two oxygen atoms. Sodium chlorite, unstable as a solid, is typically sold in a solution. The molar mass of Sodium chlorite is 90.438 g/mol. Sodium chlorite decomposes at about 180-200◦C. Madhu is a graduate in Biological Sciences with BSc (Honours) Degree and currently persuing a Masters Degree in Industrial and Environmental Chemistry. 5. -20 0 20 40 60 80 100 120 140 160 180 The melting point of sodium hypochlorite is 18°C and the boiling point is 101◦C. A few drops of solution are added to drinking water with an acid buffer such as citric acid. (adsbygoogle = window.adsbygoogle || []).push({}); Copyright © 2010-2018 Difference Between. Sodium hypochlorite is a sodium salt of hypochlorous acid. It also finds its use in many industrial applications such as paper and textiles. Its chemical formula is NaClO2 -- similar to sodium chloride but with oxygen attached to the molecule as well. It also has a sweet odor. The chlorite ion, or chlorine dioxide anion, is the halite with the chemical formula of ClO − 2.A chlorite (compound) is a compound that contains this group, with chlorine in the oxidation state of +3. But the sodium salt of this acid is very stable and also inexpensive. Similarities Between Sodium Chlorite and Sodium Hypochlorite 3. All rights reserved. It is an ionic compound that contains a sodium cation (Na+) and chlorite anion (ClO2–). Sodium chloride and sodium chlorite, despite having very similar names, are quite different substances with different uses. "Chlorate", when followed by a Roman numeral in parentheses, e.g. Large caverns and mines of table salt exist around the world. It is the most abundant form of salt in seawater, although seawater contains other salts as well. The key difference between sodium chlorite and sodium hypochlorite is that sodium chlorite contains chlorine atoms having +3 oxidation state whereas sodium hypochlorite contains chlorine atoms having +1 oxidation state. Eng.(Vol. Chlorites are also known as salts of chlorous acid This compound has de-staining properties; hence it is used to remove mold stains, dental stains, etc. Concentration was measured in every 10 injections. Chlorine dioxide is very volatile and is The burning of sodium chlorite is difficult, but it can accelerate the burning of organic compounds. @media (max-width: 1171px) { .sidead300 { margin-left: -20px; } }
Most of the times, sodium chlorite is derived from sodium chlorate, which has the chemical formula NaClO3. Sodium chlorite is an inorganic chemical compound having the chemical formula NaClO2. Sodium hypochlorite is a good disinfectant since it has a broad range of anti-microbial activity. 3. Sodium chlorite and sodium hypochlorite are common sodium salts used in industries. 2. Sodium Chlorite vs Sodium Hypochlorite: Sodium chlorite is an inorganic chemical compound having the chemical formula NaClO 2. The molecular makeup of the two substances is different, which gives them different chemical properties. The atomic ratio between sodium, chlorine and oxygen is 1:1:1. Chloride standard concentrations vs. area of peak around 4.1 minutes (♦). Sodium chlorite is a sodium salt of chlorous acid. Figure 6. It is a large-scale, industrial method. Sodium chlorite is mainly used in the manufacturing of paper and also as a disinfectant.
