**Understanding pH and pOH Levels**

This section explores various pH and pOH levels, as well as their respective hydrogen ion concentrations:

a. **pH = 4.5**  
   - This value indicates a mildly acidic solution.

b. **pH = 13.1**  
   - This value corresponds to a strongly basic or alkaline solution.

c. **pH = 7.0**  
   - A neutral pH level, typical for pure water.

d. **pOH = 1.0**  
   - Indicates a highly basic solution.

e. **pOH = 9.2**  
   - Represents a mildly acidic solution.

f. **[H⁺] = 3.4 x 10⁻⁵ M**  
   - The hydrogen ion concentration is given in molarity, indicating an acidic solution.

g. **[H⁺] = 6.8 x 10⁻⁹ M**  
   - Reflects a basic solution given the low concentration of hydrogen ions.

h. **[OH⁻] = 0.10 M**  
   - The hydroxide ion concentration suggests a strongly basic solution.

Understanding these values helps in determining the acidic or basic nature of the solutions, which is crucial in various scientific and industrial applications.
