Question

What is the net ionic equation for Al(OH)3 (s) + 3HBr (aq) = AlBr3 (aq) + 3H2O (l)

Answer 1

Al(OH)3+3H+3Br=Al+3Br+H2O. Cancel 3Br both sides
Al(OH)3+3H=Al+2H2O

Answer 2

`Al(OH)_(3)(s)+3H^(+)(aq.)=Al^(3+)(aq.)+3H_(2)O(l)`

Step-by-step explanation:

• Net ionic equations are written by omitting same ions present in both side of total ionic equation.
• HBr and
  `AlBr_(3)` are strong electrolytes. Therefore they are fully dissociated in aqueous solution.
• Total ionic equation:
  `Al(OH)_(3)(s)+3H^(+)(aq.)+3Br^(-)(aq.)=Al^(3+)(aq.)+3Br^(-)(aq.)+3H_(2)O(l)`
• Net ionic equation (by omitting
  `Br^(-)` from both side):

`Al(OH)_(3)(s)+3H^(+)(aq.)=Al^(3+)(aq.)+3H_(2)O(l)`
