Question

When chlorine and sodium hydroxide being produced during the electrolysis of brine are allowed to mix, a new chemical is formed. Name the chemical and write its uses.

Answer 1

We need to know the reaction between chlorine and sodium hydroxide and study the new chemical that is formed. Chlorine is a chemical element with the atomic number $17$ and the symbol $Cl$. It is the second-lightest of the halogens, appearing in the periodic table between fluorine and bromine, and its properties are often intermediate between them. At room temperature, chlorine is a yellow-green gas. The inorganic compound sodium hydroxide, also known as lye or caustic soda, has the formula $NaOH$. It's a white ionic compound made up of sodium cations $N{a^ + }$and hydroxide anions $O{H^ - }$.

Complete answer:
We have to know that when chlorine and sodium hydroxide, which are released during brine electrolysis, are allowed to mix, Sodium hypochlorite is formed. The molecular formula for it is $NaClO$.
The uses of Sodium hypochlorite are as follows:
In general, household bleach is a solution containing $3 - 8\%$ sodium hypochlorite by weight and $0.01 - 0.05$ percent sodium hydroxide, with the sodium hydroxide slowing the decomposition of sodium hypochlorite into sodium chloride and sodium chlorate.
Destaining properties of sodium hypochlorite It can be used to remove mould stains, dental stains caused by fluorosis, and stains on crockery, especially those caused by the tannins in tea, among other things. It's also been used as a surface cleaner and in laundry detergents.
Sodium hypochlorite in solution has broad antimicrobial potential and is commonly used in a number of settings in healthcare facilities.
Deodorizing properties of sodium hypochlorite go hand in hand with its cleaning abilities.
Dilute cyanide waste water, such as electroplating wastes, has been treated with sodium hypochlorite solutions. Sodium hypochlorite has been used to treat more concentrated cyanide wastes, such as silver cyanide plating solutions, in batch treatment operations.

Note:
We must note that Sodium hypochlorite can also be thought of as hypochlorous acid's sodium salt. The anhydrous compound is unstable and could explode if it decomposes. It can be crystallised as $NaOC{l_5} \cdot {H_2}O$, a pale greenish-yellow solid that is non-explosive and stable when held refrigerated. Oxidation and hydrolysis are responsible for its bleaching, drying, deodorising, and caustic properties (saponification).
