## What is the pH and pOH?

**pH:** pH is a measure of the acidity or alkalinity of a solution. It represents the concentration of hydrogen ions (H^{+}) in a solution. pH values range from 0 to 14, where:

- pH < 7 indicates acidity (more H
^{+}ions). - pH = 7 denotes neutrality (equal concentrations of H
^{+}and OH^{–}ions). - pH > 7 signifies alkalinity (more OH
^{–}ions).

**pOH:** pOH is the negative logarithm (base 10) of the hydroxide ion (OH^{–}) concentration in a solution. It’s related to pH by the equation pH + pOH = 14 in aqueous solutions at 25°C. Similar to pH:

- pOH < 7 indicates basic solutions (more OH
^{–}ions). - pOH = 7 is neutral.
- pOH > 7 represents acidic solutions (more H
^{+}ions).

## Calculation:

**pOH Calculation from pH:** To convert pH to pOH, subtract the pH value from 14: pOH = 14 – pH.

**Example: Convert pH to pOH**

**Given:**pH = 4.2**Calculation:**pOH = 14 − pH = 14 − 4.2 = 9.8.**Result:**For a solution with a pH of 4.2, the corresponding pOH is approximately 9.8.

These examples demonstrate the straightforward conversion between pH and pOH using the relationship pH + pOH = 14 in aqueous solutions at 25°C.

**pH Calculation from pOH:** To convert pOH to pH, subtract the pOH value from 14: pH = 14 – pOH.

**Example: Convert pOH to pH**

**Given:**pOH = 10.5**Calculation:**pH = 14 − pOH = 14 − 10.5 = 3.5**Result:**For a solution with a pOH of 10.5, the corresponding pH is approximately 3.5.

These examples demonstrate the straightforward conversion between pH and pOH using the relationship pH + pOH = 14 in aqueous solutions at 25°C.
