Answer: OPTION, D

Explanation:

It is an example for ionic salt and has Calcium ion and sulfate ion.

Hence it's name is Calcium sulfate.

Calcium sulfoxide does not exist.

Calcium sulfite has CaSO3.

Answer: The name of [tex]CaSO_4[/tex] is calcium sulfate.

Explanation:

An ionic compound is defined as the compound which is formed when electron gets transferred from one atom to another atom. These are usually formed when a metal reacts with a non-metal or a metal reacts with a polyatomic ion or a reaction between two polyatomic ions takes place.

[tex]CaSO_4[/tex] is an ionic compound because calcium element is a metal and sulfate ion is a polyatomic ion. The bond formed between a metal and a non-metal is always ionic in nature.

The nomenclature of ionic compounds is given by:

  • Positive ion is written first.
  • The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
  • In case of polyatomic ions, the name of the ion is written as such. For Example: [tex]OH^-[/tex] is named as hydroxide, [tex]SO_4^{2-}[/tex] is named as sulfate and so on..

Hence, the name of [tex]CaSO_4[/tex] is calcium sulfate.
