How do you write the chemical equation for neutralization of nitric acid, HNO3, with magnesium hydroxide, Mg (OH)2, first with spectator ions and then without spectator ions?
The molecular equation is
2HNO3 + Mg(OH)2 ==> Mg(NO3)2 + 2H2O. If these are in solution (the problem doesn't say that but the implication is that they are, then
2HNO3(aq) + Mg(OH)2(aq) ==> Mg(NO3)2(aq) + 2H2O(l)
Net ionic equation is
2H^+ + 2OH^- ==> 2H2O and if you really want to do it up brown you write
2H^+(aq) + 2OH^-(aq) ==> 2H2O(l)
To write the chemical equation for the neutralization of nitric acid (HNO3) with magnesium hydroxide (Mg(OH)2), we need to understand the reaction between the acid and base. Neutralization reactions occur when an acid reacts with a base, resulting in the formation of water and a salt.
1. Writing the chemical equation with spectator ions:
In this step, we include all the ions present in the solution, even if they do not participate in the reaction.
The balanced molecular equation for the neutralization of nitric acid with magnesium hydroxide is:
2HNO3 + Mg(OH)2 → Mg(NO3)2 + 2H2O
Here, we can see that two molecules of nitric acid react with one molecule of magnesium hydroxide to produce one molecule of magnesium nitrate and two molecules of water.
2. Writing the chemical equation without spectator ions:
In this step, we exclude the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction.
Balanced net ionic equation for the neutralization of nitric acid with magnesium hydroxide:
2H+ + 2OH- → 2H2O
In this equation, we only include the ions that participate in the reaction. Two hydrogen ions from the nitric acid react with two hydroxide ions from the magnesium hydroxide to form water.
It's important to note that balancing equations involves ensuring the number of atoms on both sides of the equation is equal. You can verify the validity of the equations using a chemical equation balancing calculator or process.
To write the chemical equation for the neutralization of nitric acid (HNO3) with magnesium hydroxide (Mg(OH)2), we first need to determine the balanced chemical equation.
1. Neutralization with Spectator Ions:
In this case, the spectator ions are the ions that do not participate in the chemical reaction and remain unchanged throughout the process.
Step 1: Write the formula for the reactants:
HNO3 + Mg(OH)2
Step 2: Determine the products:
The reaction between an acid and a base always produces water (H2O) and a salt.
The salt will contain the positive ion from the base (Mg2+) and the negative ion from the acid (NO3-).
Step 3: Write the balanced equation:
HNO3 + Mg(OH)2 → Mg(NO3)2 + H2O
2. Neutralization without Spectator Ions:
If we exclude spectator ions, we only include the participating ions in the chemical reaction.
Step 1: Write the formula for the reactants:
H+ + NO3- + Mg2+ + 2OH-
Step 2: Determine the products:
The reaction will result in the formation of water (H2O) and a salt containing the metal ion from the base (Mg2+) and the non-metal ion from the acid (NO3-).
Step 3: Write the balanced equation:
2H+ + 2OH- + Mg2+ + 2NO3- → Mg(NO3)2 + 2H2O
Note: In both cases, the H+ ion from the acid and OH- ion from the base combine to form water, while the remaining ions form the salt.
