D
Al(C2H3O2)2
Verified step by step guidance
1
Identify the charge on the aluminum ion. Aluminum typically forms a +3 charge, so its ion is Al^{3+}.
Determine the formula and charge of the acetate ion. Acetate is C2H3O2^{-} with a -1 charge.
Balance the total positive and negative charges to form a neutral compound. Since aluminum is +3 and acetate is -1, you need three acetate ions to balance one aluminum ion.
Write the chemical formula by placing the aluminum ion first, followed by the acetate ion in parentheses with a subscript indicating the number of acetate ions needed to balance the charge.
The correct formula is Al(C2H3O2)3, showing one aluminum ion combined with three acetate ions to maintain electrical neutrality.
