Question

What are the missing coefficients in the skeleton equation:

Al₂(SO₄)₃(aq) + KOH(aq) → Al(OH)₃(aq) + K₂SO₄(aq)?

A) 2, 6, 2, 3
B) 2, 3, 2, 3
C) 1, 6, 2, 3
D) 1, 3, 2, 3

Answer 1

To balance the equation Al₂(SO₄)₃(aq) + KOH(aq) → Al(OH)₃(aq) + K₂SO₄(aq), the missing coefficients are 2, 6, 2, 3.

Step-by-step explanation:

To balance the equation Al₂(SO₄)₃(aq) + KOH(aq) → Al(OH)₃(aq) + K₂SO₄(aq), we need to make sure the number of atoms of each element is the same on both sides of the equation. Here are the missing coefficients:

Al₂(SO₄)₃(aq) + 6KOH(aq) → 2Al(OH)₃(aq) + 3K₂SO₄(aq)

So the answer is option A) 2, 6, 2, 3.
