Verified step by step guidance
1
Identify the chemical formula of the compound, which is Al(OH)\_3. This notation shows the composition of the compound in terms of ions or groups.
Recognize that the subscript outside the parentheses applies to everything inside the parentheses. Here, the subscript 3 applies to the hydroxide ion (OH) group.
Understand that the hydroxide ion is represented as OH\^-, which means each hydroxide ion consists of one oxygen and one hydrogen atom and carries a single negative charge.
Since the formula is Al(OH)\_3, it means there are 3 hydroxide ions bonded to each aluminum ion in the compound.
Therefore, the number of hydroxide ions bonded to each aluminum ion is 3.
