The answer to your question is the second option
Explanation:
Reaction
Al₂(SO₄)₃ + KOH ⇒ Al(OH)₃ + K₂SO₄
Process
1.- Check if the reaction is already balanced
Reactants Elements Products
2 Aluminum 1
3 Sulfur 1
13 Oxygen 7
1 Potassium 2
1 Hydrogen 3
The reaction is unbalanced
2.- Balance the reaction
1Al₂(SO₄)₃ + 6KOH ⇒ 2Al(OH)₃ + 3K₂SO₄
Reactants Elements Products
2 Aluminum 2
3 Sulfur 3
18 Oxygen 18
6 Potassium 6
6 Hydrogen 6
Now the reaction is balanced. The coefficients are 1, 6, 2, 3.
