### Chemical Reactions and Equations in Aqueous Solutions

**Problem:**  
Write the balanced complete molecular, complete ionic, and net ionic chemical equations including phase labels for the neutralization of solid potassium hydroxide with aqueous sulfuric acid. Include phase labels.

**Solution:**

1. **Balanced Complete Molecular Equation:**
\[ 2 \text{KOH(s)} + \text{H}_2\text{SO}_4\text{(aq)} \rightarrow \text{K}_2\text{SO}_4\text{(aq)} + 2 \text{H}_2\text{O(l)} \]

2. **Balanced Complete Ionic Equation:**
\[ 2 \text{K}^+ (\text{aq}) + 2 \text{OH}^- (\text{aq}) + 2 \text{H}^+ (\text{aq}) + \text{SO}_4^{2-} (\text{aq}) \rightarrow 2 \text{K}^+ (\text{aq}) + \text{SO}_4^{2-} (\text{aq}) + 2 \text{H}_2\text{O(l)} \]

3. **Net Ionic Equation:**
\[ 2 \text{OH}^- (\text{aq}) + 2 \text{H}^+ (\text{aq}) \rightarrow 2 \text{H}_2\text{O(l)} \]

In these equations:

- **Phase Labels:**
  - **s** stands for solid.
  - **l** stands for liquid.
  - **aq** stands for aqueous, indicating that the substance is dissolved in water.

Understanding these types of equations is critical for mastering the reactions that occur in aqueous solutions, especially in fields like chemistry and environmental science.
