1. What is the pH Scale?

The pH scale is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. As mentioned earlier, it ranges from 0 to 14. At a pH of 7, a solution is considered neutral; anything below 7 indicates that the solution is acidic, while anything above 7 indicates that it is alkaline. The scale is based on the concentration of hydrogen ions (H⁺) present in the solution:

1. **Acids**: Substances with a pH less than 7 contain a higher concentration of hydrogen ions. Common examples include stomach acid (with a pH around 1-3) and vinegar (around 2-3).

2. **Neutral**: Pure water is an example of a neutral solution, which serves as a reference point for the pH scale. It has a balanced concentration of hydroxide ions (OH⁻) and hydrogen ions.

3. **Bases**: Substances with a pH greater than 7 contain a lower concentration of hydrogen ions and hence are called alkaline solutions. Examples include household ammonia (about 11-12) and sodium hydroxide (around 13-14).

The relationship between pH and hydrogen ion concentration is defined by the formula:

pH = -log[H⁺]

Thus, a change of one unit on the pH scale corresponds to a tenfold change in acidity or alkalinity. For instance, a solution with a pH of 5 is ten times more acidic than one with a pH of 6. Understanding the scale is crucial in fields ranging from agriculture to medicine, as it affects how substances behave in various chemical reactions.
