What defines a basic solution in terms of pH?

A basic solution is characterized by a pH value greater than 7. The pH scale ranges from 0 to 14, where 7 is considered neutral (pure water). Values below 7 indicate acidic solutions, while values above 7 indicate basic (or alkaline) solutions. In a basic solution, the concentration of hydroxide ions (OH-) is greater than the concentration of hydrogen ions (H+), which shifts the pH above the neutral point. It's important to note that while a pH value of 14 represents a strongly basic solution, not all basic solutions will reach this high level; any pH above 7 is sufficient to classify a solution as basic.
