Question

Complete and balance the following reaction
hydrobromic acid plus aluminum hydroxide

Answer 1

3 HBr + Al(OH)₃ ⇒ AlBr₃ + 3 H₂O

Step-by-step explanation:

Let's consider the unbalanced equation for the reaction that takes place when hydrobromic acid reacts with aluminum hydroxide. This is a neutralization reaction, in which an acid reacts with a base to produce a salt and water.

HBr + Al(OH)₃ ⇒ AlBr₃ + H₂O

First, we will balance Br atoms by multiplying HBr by 3.

3 HBr + Al(OH)₃ ⇒ AlBr₃ + H₂O

Finally, we get the balanced equation by multiplying H₂O by 3.

3 HBr + Al(OH)₃ ⇒ AlBr₃ + 3 H₂O
