In the compound Al(OH)3, how many hydroxide ions are bonded to each aluminum ion?A3B4C1D2

Break Down the Problem

1. Identify the chemical formula Al(OH)₃.
2. Determine the relationship between aluminum ions and hydroxide ions in the formula.

Relevant Concepts

• The formula Al(OH)₃ indicates that for every 1 aluminum ion (Al³⁺), there are 3 hydroxide ions (OH⁻) associated with it.

Analysis and Detail

1. Chemical Composition: The compound Al(OH)₃ consists of:
   • Aluminum (Al) ion: 1
   • Hydroxide (OH) ions: 3
2. Each aluminum ion is surrounded by hydroxide ions, which means:
   • The number of hydroxide ions per aluminum ion is directly taken from the subscript in the formula.

Verify and Summarize

• Since there are 3 hydroxide ions (OH) for 1 aluminum ion (Al), we can confirm that the relationship is correct.

Final Answer

Each aluminum ion in Al(OH)₃ is bonded to 3 hydroxide ions. Therefore, the correct answer is A: 3.
