The pH and pOH Relationship Calculator is designed to help determine the acidity or basicity of a solution based on the equation pH + pOH = 14. This relationship between pH and pOH indicates the balance of hydrogen and hydroxide ions in any solution, providing insight into its acidic or alkaline nature.

### How to Use the Calculator

**Enter Known Values**: Input either the **pH** or **pOH** value.
**Calculate the Result**: Using the relationship formula, this tool will calculate the missing value, ensuring pH + pOH equals 14.
**Interpret the Result**: This balance indicates whether the solution is acidic, neutral, or basic.

**Key Definitions**

**Term** |
**Description** |

**pH** |
Measures acidity; lower values indicate more acidic solutions, while higher values indicate more basic solutions. |

**pOH** |
Measures basicity; lower values indicate a less basic solution, and higher values suggest greater alkalinity. |

### Step-by-Step Calculation Examples

**Example 1**: Calculate pOH When pH is Known

**Step** |
**Calculation** |

**Given** |
pH = 6.5 |

**Formula** |
pH + pOH = 14 |

**Calculation** |
pOH = 14 – pH |

**Result** |
pOH = 14 – 6.5 = 7.5 |

The result shows that if the pH is 6.5, then the pOH is **7.5**, indicating a slightly acidic solution.

**Example 2**: Calculate pH When pOH is Known

**Step** |
**Calculation** |

**Given** |
pOH = 8 |

**Formula** |
pH + pOH = 14 |

**Calculation** |
pH = 14 – pOH |

**Result** |
pH = 14 – 8 = 6 |

With a pOH of 8, the pH is **6**, which shows the solution is slightly acidic.

**Summary of Input Fields**

**Field** |
**Description** |

**pH Value** |
Input the pH value if known; represents solution acidity. |

**pOH Value** |
Input the pOH value if known; represents solution basicity. |

**Result** |
Displays the calculated value to complete the pH + pOH = 14 relationship. |

This tool provides a straightforward way to analyze solutions, whether in chemistry studies or general scientific applications, making it easy to understand the relationship between pH and pOH in a solution.
