Question

what is the name of this ionic compound? al(oh)3 aluminum oxohy dride aluminum hydroxide aluminum hydroxygen aluminum tri - hydroxide

Explanation:

Ionic compounds are named by stating the cation first, followed by the anion. In \(Al(OH)_3\), the cation is \(Al^{3+}\) (aluminum ion) and the anion is \(OH^-\) (hydroxide ion). The standard naming convention for such compounds with the hydroxide anion is to call it "aluminum hydroxide". The other options are either non - standard (e.g., "aluminum oxohy dride" is not the common name, "aluminum hydroxygen" is an incorrect term as it misrepresents the hydroxide ion, and "aluminum tri - hydroxide" is not the typical way to name ionic compounds with hydroxide anions; the subscript is accounted for in the charge balance during formula writing, not in the naming with a prefix like "tri -" in the common naming of simple ionic compounds).

Answer:

aluminum hydroxide
