How would you complete and balance the acid base neutralizations reaction: HBr + Ba(OH)_2 ->?
1 Answer
Explanation:
In a neutralization reaction, if the base is a hydroxide, then the products formed would be the salt and water.
acid + base
-> salt + water
The water (
The salt (
The unbalanced equation is therefore
"HBr" + "Ba(OH)"_2 -> "BaBr"_2 + "H"_2"O"
To balance the equation, first notice that the number of Ba on both sides are the same. Ba is balanced.
Next, notice that the LHS is short of 1 x Br. So balance it by adding 1 unit of HBr.
"2HBr" + "Ba(OH)"_2 -> "BaBr"_2 + "H"_2"O"
Now, the RHS is missing 2 x H and 1 x O. Balance that by adding 1 units of
"2HBr" + "Ba(OH)"_2 -> "BaBr"_2 + 2"H"_2"O"
Now, all the elements have equal amounts on both sides of the equation. The chemical equation is now considered balanced.
