Key Concepts

pH Scale

The pH scale is a numerical system used to specify the acidity or basicity (alkalinity) of an aqueous solution. A pH less than 7 indicates an acidic solution, a pH of 7 is neutral, and a pH greater than 7 indicates a basic solution.

Acids

Acids are substances that donate protons (H? ions) when dissolved in water, often exhibiting a sour taste and the ability to change the color of pH indicators. They have pH values below 7.

Bases

Bases are substances that accept protons or release hydroxide ions (OH?) in water, generally characterized by a bitter taste, slippery feel, and pH values above 7. Their interaction with indicators often results in color changes distinct from those seen with acids.

Indicators

pH indicators, such as cabbage juice that changes color depending on the pH of the solution, are used to determine the acidic or basic nature of a solution. These indicators provide a visual cue by changing color in response to the concentration of hydrogen or hydroxide ions.

Sensory Observations

Sensory observations, including taste and texture, can provide clues about a solution's pH. For example, a sour taste typically suggests an acidic solution, while a slippery feel indicates the presence of a base.
