What term describes aqueous solutions with a pH above 7?

Aqueous solutions with a pH above 7 are classified as bases. The pH scale ranges from 0 to 14, where a pH of 7 is considered neutral, indicating an equal concentration of hydrogen ions (H⁺) and hydroxide ions (OH⁻). When the pH is above 7, it signals that the concentration of hydroxide ions is higher than that of hydrogen ions, a characteristic property of basic solutions. Bases can accept hydrogen ions or donate hydroxide ions in a reaction, resulting in a higher pH. This understanding is fundamental in concepts such as acid-base chemistry, leading to applications in various scientific fields, including biology and environmental science.
