An acidity and basicity calculator helps determine the pH or pOH of a solution, indicating whether the solution is acidic, basic, or neutral. It uses input data such as hydrogen ion ($H^+$) or hydroxide ion ($OH^-$) concentrations to compute pH and pOH values for better understanding of chemical properties.

This tool is essential in laboratory experiments, industrial processes, environmental monitoring, and education.

How to Use the Acidity and Basicity Calculator

Step 1: Input Required Parameters

Provide the following data:

• Concentration of $H^+$ or $OH^-$ ions (in mol/L)
• Indicate whether you want to calculate pH or pOH

Step 2: Perform Calculation

The calculator applies these formulas:

$$pH = -\log [H^+]$$ $$pOH = -\log [OH^-]$$

Additionally, it follows the relationship:

$$pH + pOH = 14$$

Example Calculation

If the $H^+$ ion concentration is $1 \times 10^{-4}$ mol/L, the calculator computes:

$$pH = -\log(1 \times 10^{-4}) = 4$$

Since $pH + pOH = 14$, the corresponding pOH is 10.
