Question

What happens when the following are heated? Lithium nitrate

Answer 1

$LiN{O_3}$ is a lithium nitrate chemical. It is the lithium nitrate salt, which is an inorganic chemical. When heated, this chemical undergoes a breakdown reaction, resulting in the formation of lithium oxide and nitrogen dioxide.

Complete answer: The inorganic chemical lithium nitrate has the formula $LiN{O_3}$ . It's nitric acid's lithium salt (an alkali metal nitrate). The salt is deliquescent, absorbing water to form lithium nitrate trihydrate, the hydrated form. Heat transfer fluids are interested in its eutectics.
Lithium oxy-salts are heat unstable and break down when heated, forming the stable oxide.
Lithium nitrate decomposes into lithium oxide, nitrogen dioxide, and oxygen when heated.
$2LiN{O_3} \to L{i_2}O + 2N{O_2} + \dfrac{1}{2}{O_2}$

Additional information:
Nitric acid and lithium carbonate can be used to make lithium nitrate.
$L{i_2}C{O_3}\; + {\text{ }}2{\text{ }}HN{O_3}\; \to {\text{ }}2{\text{ }}LiN{O_3}\; + {\text{ }}{H_2}O{\text{ }} + {\text{ }}C{O_2}$
A pH indicator is usually used to identify when all of the acid has been neutralised when making$LiN{O_3}$ . However, the lack of carbon dioxide generation can also be seen as a sign of neutralisation. The sample is heated to remove surplus water from the final product.
At ambient temperature, lithium does not react with oxygen, but it does so at temperatures above$100^\circ C$ , forming lithium oxide $\left( {L{i_2}O} \right)$ . The element can also combine with sulphur, hydrogen, nitrogen, and the halogens under the right conditions.

Note:
When swallowed, lithium nitrate can cause harm to the central nervous system, thyroid glands, kidneys, and cardiovascular system. Lithium nitrate can irritate the skin, eyes, and mucous membranes when they are exposed to it.
