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.\

Explanation:

Ionic bases typically consist of a cation and the hydroxide polyatomic ion ($\text{OH}^-$). By definition, their naming convention requires the name to conclude with "hydroxide" to denote the presence of this ion. The other options describe rules for naming acids, not ionic bases.

Answer:

The chemical name ends with "hydroxide."
