Question

Write names, formula and uses of following compounds:
1. Haematite
2. Silver Glance
3. Lunar-Caustic
4. Corrosive Sublimate

Answer 1

Hint: The chemical name is the name of a chemical compound that shows the name of each of its constituent sub compounds or elements. The chemical formula is a short way of representing the chemical name. It also presents the information about the chemical proportions of the atoms that constitute a particular compound.

Complete answer:
Let us look at the chemical names, formulas and uses of the given:
1. Heamatite:
* The chemical name of Haematite is iron oxide or ferric oxide
* The chemical formula of iron oxide is ${Fe}_{2}{O}_{3}$.
* Its uses are to produce pigments, used in preparation for heavy media separation, preparation of corrosion substances, and in radiation shielding.
2. Silver Glance:
* The chemical name of silver glance is silver sulphide.
* The chemical formula of silver sulphide is ${Ag}_{2}S$.
* It is used in vessels and metallic articles, in silver salts, in preparation of ornaments etc.
3. Lunar Caustic:
* The chemical name of lunar caustic is silver nitrate.
* The chemical formula of silver nitrate is $AgN{O}_{3}$.
* It is used in silvering of mirrors, photography, as a laboratory agent and in preparation in silver halides.
4. Corrosive Sublimate:
* The chemical name of corrosive sublimate is mercuric chloride.
* The chemical formula of mercuric chloride is $HgC{l}_{2}$.
* Its dilute solution is used for sterilization of surgical instruments, and is used as wood preservative and in dry cells.

Note:
* Heamatite is a relatively hard oxide mineral that constitutes the most important part of iron ore as it has a very high concentration.
* Silver glance is a dense black solid and is the only sulphide of silver.
* Lunar caustic is a versatile persecute to other silver compounds.
* Corrosive sublimate is a white crystalline solid and a compound that is very toxic
