To calculate the hydroxide ion concentration (OH−) from pH, use the formula [OH−]=10−14+pH[OH−] = 10^{−14 + pH}.
The Ph to Oh- Calculator allows you to calculate the concentration of hydroxide ions () based on the given pH value. In essence, the pH scale measures the acidity or alkalinity of a solution, while the OH− concentration provides insight into the basicity.
For example, if you know the pH of a solution, this calculator can help you find the corresponding concentration of hydroxide ions, which is essential for understanding the solution’s properties and behavior.
Formula
| Variable | Description |
|---|---|
| [OH−] | Hydroxide ion concentration |
| pH | pH value of the solution |
Solved Calculations
Example 1:
For instance, if the pH of the solution is 5, the OH− concentration is calculated as:
| Step | Calculation |
|---|---|
| pH Value | 5 |
| OH− Concentration | |
| Result | mol/L |
Answer: The OH− concentration at pH 5 is mol/L.
Example 2:
Similarly, if the pH is 12, the OH− concentration is:
| Step | Calculation |
|---|---|
| pH Value | 12 |
| OH− Concentration | |
| Result | mol/L |
Answer: The OH− concentration at pH 12 is mol/L.
What is a pH to OH- Calculator?
The pH to OH- Calculator is a powerful pH-related tool. This tool seamlessly helps you convert pH values into the concentration of hydroxide ions (OH-). This is particularly useful in chemistry and environmental science.
Moreover, understanding the relationship between hydrogen ion concentration (pH) and hydroxide ion concentration (OH-) is crucial for analyzing the acidity or basicity of a solution. The calculator uses the relationship between pH and the concentration of OH- ions to provide a straightforward result.
To use this tool, you simply input the pH value, and the calculator will determine the corresponding OH- concentration. This calculation is based on the formula, where the product of the concentrations of H+ and OH- ions is always equal to 1 × 10^-14 at 25°C. For instance, if the pH of a solution is 5, the OH- concentration can be easily calculated using this tool.
Final Words:
In conclusion, the pH to OH- Calculator is an essential tool for anyone working with solutions in the lab, making it easier to understand and manage the relationship between acidity and basicity in various chemical contexts.
