The Ph to Oh- Calculator allows you to calculate the concentration of hydroxide ions ($[OH−]$) 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

$$[OH−] = 10^{−14 + pH}$$

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	$10^{−14 + 5}$
Result	$10^{−9}$ mol/L

Answer: The OH− concentration at pH 5 is $10^{−9}$mol/L.

Example 2:
Similarly, if the pH is 12, the OH− concentration is:

Step	Calculation
pH Value	12
OH− Concentration	$10^{−14 + 12}$
Result	$10^{−2}$ mol/L

Answer: The OH− concentration at pH 12 is $10^{−2}$ 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.
