Question

What is the common name for $N{{a}_{2}}S{{O}_{4}}.10{{H}_{2}}O$?

Answer 1

Hint: As we know that the common name of the above given chemical formula is Glauber’s salt which is the decahydrate form of sodium sulfate and is also known as mirabilite. It is known to be a vitreous mineral with a colourless or light white color appearance that is formed as it evaporates from brines which contain sodium sulfate.

Complete answer:
Let us write the common name of the given formula and discuss about it:-
-The common name of $N{{a}_{2}}S{{O}_{4}}.10{{H}_{2}}O$ is Glauber’s salt which is also known as sodium sulfate decahydrate or mirabilite.
-It is known to be a vitreous mineral with a colourless or light white color appearance that is formed as it evaporates from brines containing sodium sulfate. It can be noted that Glauber’s salt is known to occur naturally along saline playa lakes and around saline springs.
-It should be noted that this salt is quite unstable in dry air and when placed in such an environment, this compound is known to rapidly undergo dehydration. When this happens, the crystals of Glauber’s salt get converted into a white powder whose chemical formula is $N{{a}_{2}}S{{O}_{4}}$. This white powder is often known as thenardite. Also theardite is known to possess the ability to absorb water and then convert itself into mirabilite.

Note:
-Sodium sulfate decahydrate is known to crystallize in a monoclinic crystal system.
-Also it is commonly used in a variety of drugs as a laxative and in order to treat some overdose cases, this salt is particularly helpful for eliminating unnecessary drugs in the body.
