Litmus solution exhibits a purple color when it is neither acidic nor basic. In a neutral solution with a pH of around 7, litmus appears purple or violet. This is because litmus is a natural pH indicator that undergoes a color change in response to the acidity or basicity of the solution. In a neutral environment, the concentrations of hydrogen ions (H⁺) and hydroxide ions (OH⁻) are balanced, resulting in the purple color of litmus. The distinct color changes of litmus—red in acidic conditions, blue in basic conditions, and purple in neutral conditions—make it a valuable tool for qualitative assessment of pH levels.
