Write a balanced equation for the neutralization of each of the following. Express your answer as a chemical equation. Identify all of the phases in your answer.
Part A: H3PO4(aq) and NaOH(aq)
Part B: Hl(aq) and LiOH(aq)
Part C: HNO3(aq) and Ca(OH)2(aq
Memorize this:
An acid + a base yields a salt + H2O
A. H3PO4(aq) + 3NaOH(aq) ==> Na3PO4(aq) + 3H2O(l)
B and C are done the same way.
LiOH+HNO3→
Part A: H3PO4(aq) + 3NaOH(aq) → Na3PO4(aq) + 3H2O(l)
Part B: Hl(aq) + LiOH(aq) → LiI(aq) + H2O(l)
Part C: 2HNO3(aq) + Ca(OH)2(aq) → Ca(NO3)2(aq) + 2H2O(l)
To write balanced equations for the neutralization reactions, we need to combine the reactants and determine the products formed. In neutralization reactions, an acid reacts with a base to form a salt and water.
Part A: Neutralization of H3PO4(aq) and NaOH(aq)
The reactants are H3PO4(aq) (phosphoric acid) and NaOH(aq) (sodium hydroxide).
The balanced equation for the reaction is:
H3PO4(aq) + 3NaOH(aq) → Na3PO4(aq) + 3H2O(l)
Part B: Neutralization of Hl(aq) and LiOH(aq)
The reactants are Hl(aq) (hydroiodic acid) and LiOH(aq) (lithium hydroxide).
The balanced equation for the reaction is:
Hl(aq) + LiOH(aq) → LiI(aq) + H2O(l)
Part C: Neutralization of HNO3(aq) and Ca(OH)2(aq)
The reactants are HNO3(aq) (nitric acid) and Ca(OH)2(aq) (calcium hydroxide).
The balanced equation for the reaction is:
2HNO3(aq) + Ca(OH)2(aq) → Ca(NO3)2(aq) + 2H2O(l)
In each balanced equation, (aq) represents the aqueous solution, and (l) represents the liquid phase (water).
