Constructing Balanced Ionic Equations

  1. Oct 10, 2015 #1
    1. The problem statement, all variables and given/known data
    Write a balanced ionic equation for the half equations given below:
    Al----> Al^+3 + 3e-
    2H^+1 + 2e- -----> H2
    2. Relevant equations

    3. The attempt at a solution
    I think the answer is:
    2Al + 6H^+1 ----> 2Al^+3 + 3H2
    But the answer in the book is:
    4Al + 6H^+1 ----> 2Al^+3 + 3H2
    What is the correct answer?

    Answer in the book is not correctly balanced - so it is wrong.
