Balance The Following Chemical Equation:${ \text{-} \text{H}_3\text{PO}_4 + \text{KOH} \rightarrow \text{K}_3\text{PO}_4 + \text{H}_2\text{O} }$
Introduction
Balancing chemical equations is a crucial step in understanding chemical reactions. It involves making sure that the number of atoms for each element is the same on both the reactant and product sides of the equation. In this article, we will focus on balancing the chemical equation: ${ \text{-} \text{H}_3\text{PO}_4 + \text{KOH} \rightarrow \text{K}_3\text{PO}_4 + \text{H}_2\text{O} }$. This equation involves the reaction between phosphoric acid (H3PO4) and potassium hydroxide (KOH) to form potassium phosphate (K3PO4) and water (H2O).
Understanding the Chemical Equation
Before we start balancing the equation, let's take a closer look at the chemical equation and identify the reactants and products.
- Reactants: H3PO4 (phosphoric acid) and KOH (potassium hydroxide)
- Products: K3PO4 (potassium phosphate) and H2O (water)
Step 1: Count the Number of Atoms
To balance the equation, we need to count the number of atoms for each element on both the reactant and product sides.
| Element | H3PO4 | KOH | K3PO4 | H2O |
|---|---|---|---|---|
| H | 3 | 1 | 0 | 2 |
| P | 1 | 0 | 1 | 0 |
| O | 4 | 1 | 4 | 1 |
| K | 0 | 1 | 3 | 0 |
Step 2: Balance the Hydrogen Atoms
The first step in balancing the equation is to balance the hydrogen atoms. We can see that there are 3 hydrogen atoms on the reactant side and 2 hydrogen atoms on the product side. To balance the hydrogen atoms, we need to add a coefficient of 2 in front of H3PO4.
Step 3: Balance the Phosphorus Atoms
Next, we need to balance the phosphorus atoms. We can see that there is 1 phosphorus atom on the reactant side and 1 phosphorus atom on the product side. Since the number of phosphorus atoms is already balanced, we don't need to add any coefficients.
Step 4: Balance the Oxygen Atoms
Now, let's balance the oxygen atoms. We can see that there are 4 oxygen atoms on the reactant side and 1 oxygen atom on the product side. To balance the oxygen atoms, we need to add a coefficient of 4 in front of H2O.
Step 5: Balance the Potassium Atoms
Finally, we need to balance the potassium atoms. We can see that there is 1 potassium atom on the reactant side and 3 potassium atoms on the product side. To balance the potassium atoms, we need to add a coefficient of 3 in front of KOH.

Balancing Chemical Equations: A Q&A Guide =====================================================
Introduction
Balancing chemical equations is a crucial step in understanding chemical reactions. In our previous article, we provided a step-by-step guide on how to balance the chemical equation: ${ \text{-} \text{H}_3\text{PO}_4 + \text{KOH} \rightarrow \text{K}_3\text{PO}_4 + \text{H}_2\text{O} }$. In this article, we will answer some of the most frequently asked questions about balancing chemical equations.
Q: What is the purpose of balancing chemical equations?
A: The purpose of balancing chemical equations is to ensure that the number of atoms for each element is the same on both the reactant and product sides of the equation. This is important because it allows us to understand the stoichiometry of the reaction, which is the quantitative relationship between the reactants and products.
Q: How do I know if a chemical equation is balanced?
A: To determine if a chemical equation is balanced, you need to count the number of atoms for each element on both the reactant and product sides of the equation. If the number of atoms for each element is the same on both sides, then the equation is balanced.
Q: What are the steps to balance a chemical equation?
A: The steps to balance a chemical equation are:
- Count the number of atoms for each element on both the reactant and product sides of the equation.
- Balance the atoms one element at a time.
- Use coefficients to balance the atoms.
- Check your work by counting the number of atoms for each element on both the reactant and product sides of the equation.
Q: What is a coefficient?
A: A coefficient is a number that is placed in front of a formula to indicate the number of molecules of that substance that are present.
Q: How do I choose which element to balance first?
A: When balancing a chemical equation, it is best to start with the element that appears in the fewest number of compounds. This will make it easier to balance the equation.
Q: What if I make a mistake when balancing a chemical equation?
A: If you make a mistake when balancing a chemical equation, don't worry! It's easy to correct. Simply go back to the previous step and try again.
Q: Can I use a calculator to balance a chemical equation?
A: Yes, you can use a calculator to balance a chemical equation. However, it's always a good idea to double-check your work by counting the number of atoms for each element on both the reactant and product sides of the equation.
Q: Are there any shortcuts for balancing chemical equations?
A: Yes, there are several shortcuts for balancing chemical equations. One common shortcut is to use the "half-reaction method." This involves breaking the equation into two half-reactions and balancing each half-reaction separately.
Q: Can I balance a chemical equation that has multiple reactants or products?
A: Yes, you can balance a chemical equation that has multiple reactants or products. Simply follow the same steps as before, but be sure to count the number of atoms for each element on both the reactant and product sides of the equation.
Q: Are there any online tools or resources that can help me balance a chemical equation?
A: Yes, there are several online tools and resources that can help you balance a chemical equation. Some popular options include:
- Online balancing tools, such as the one provided by the American Chemical Society.
- Chemistry software, such as ChemDraw or ChemSketch.
- Online tutorials and videos, such as those provided by Khan Academy or Crash Course.
Conclusion
Balancing chemical equations is a crucial step in understanding chemical reactions. By following the steps outlined in this article, you should be able to balance even the most complex chemical equations.
