Which rule is used for writing the name of an ionic base?

The chemical name begins with "hydro."

The chemical name ends with "hydroxide."

The "ide" ending is changed to "ic."

The polyatomic "ate" ending is changed to "ic."

When we name ionic compounds, we write the name of the metal first and then the name of nonmetal.

The ion with the lower oxidation state is given an - ous ending, and the ion with the higher oxidation state is given an - ic ending.

Hence,

The right answer is:

The chemical name ends with "hydroxide."

The correct answer is (B) : the chemical name begins with "hydroxide"

The explanation:

1 - we write the name of the metal first and after that write the nonmetal:

Ex : NaOH (sodium hydroxide)

2 - any compound contains OH group is an ionic base and this group called hydroxide group

3 - "Ous" ending is given in the ions with the lower oxidation.

4 - " ic" ending is given in the ions with the higher oxidation.

so (B) is the correct answer.
