what is the following reaction?
HNO3(aq) + KOH(aq) ---> KNO3(aq) + H2O(l)
A neutralization?
An acid/base reaction?
The reaction you provided is a neutralization reaction between nitric acid (HNO3) and potassium hydroxide (KOH).
Step 1: Write the balanced equation:
HNO3(aq) + KOH(aq) → KNO3(aq) + H2O(l)
Step 2: Identify the reactants and the products:
Reactants: HNO3(aq) and KOH(aq)
Products: KNO3(aq) and H2O(l)
Step 3: Determine the balanced chemical equation:
The number of atoms in the reactants and products should be the same on both sides of the equation.
To balance the equation, we need one nitrogen atom in the reactant to match one nitrogen atom in the product, and one oxygen atom in the reactant to match one oxygen atom in the product.
HNO3(aq) + KOH(aq) → KNO3(aq) + H2O(l)
1 nitrogen atom on each side, balanced
3 oxygen atoms on the left, 3 oxygen atoms on the right, balanced
1 hydrogen atom on each side, balanced
1 potassium atom on each side, balanced
1 hydroxide ion on the left, 1 hydroxide ion on the right, balanced
Therefore, the balanced equation for the reaction is:
HNO3(aq) + KOH(aq) → KNO3(aq) + H2O(l)
The given reaction is a chemical equation that represents a reaction between nitric acid (HNO3) and potassium hydroxide (KOH). It produces potassium nitrate (KNO3) and water (H2O).
To understand this reaction, it is important to recognize the nature of the reactants. HNO3 is an acid known as nitric acid, and KOH is a base known as potassium hydroxide. When an acid and base react, they undergo a chemical reaction called neutralization.
In this neutralization reaction, the hydrogen ions (H+) from the nitric acid combine with the hydroxide ions (OH-) from the potassium hydroxide to form water. This is shown by the formula H2O in the product side of the equation.
The remaining ions, K+ from KOH and NO3- from HNO3, combine to form potassium nitrate, KNO3. This compound remains in solution as an aqueous (aq) salt.
The balanced chemical equation for this reaction is:
HNO3(aq) + KOH(aq) → KNO3(aq) + H2O(l)
To balance the equation, you need to ensure that the number of atoms of each element is the same on both sides of the equation. In this case, the equation is already balanced.
To determine the products of the reaction, you need to know the charges of the ions involved and the solubility rules for different salts. In this case, potassium nitrate is soluble in water, so it remains in solution.
To verify this information, you can consult reliable chemical reference sources or use chemical equation balancer tools which can help balance and provide information about the reactants and products.
