Answer:

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.
