Verified step by step guidance1
Identify the chemical formula given: Al(OH)\_3, which represents aluminum hydroxide.
Recognize that the subscript outside the parentheses applies to the entire hydroxide group (OH), indicating there are 3 hydroxide groups.
Understand that in this compound, the aluminum ion (Al) is bonded to hydroxide ions (OH\-) to balance the charge.
Since the formula shows Al(OH)\_3, it means each aluminum ion is bonded to 3 hydroxide ions.
Therefore, the number of hydroxide ions bonded to each aluminum ion is equal to the subscript 3.
