Answer :

Answer:

[tex]Co(NO_3)_2[/tex] is formed of cation, [tex]Co^{2+}[/tex] and anion,[tex]NO_3^{-}[/tex]

Explanation:

Naming of the ionic compounds:-

  • The name of the cation is written first and the the name of the anion is written after the name of the cation separated by single space.
  • 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 transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.

Hence, given ionic compound:-

[tex]Co(NO_3)_2[/tex] is formed of cation, [tex]Co^{2+}[/tex] and anion,[tex]NO_3^{-}[/tex]

Thus, the name must be Cobalt(II) nitrate.
