A substance with a pH greater than 7 is best described as a

pH expresses how acidic or basic a solution is. When pH is greater than 7, the solution is basic (alkaline). A base describes substances that raise pH by either delivering hydroxide ions or by accepting protons in water. Therefore, a substance with pH above 7 is best described as a base. Acids have pH below 7, neutral solutions are around pH 7, and salts can yield acidic, basic, or neutral solutions depending on the ions involved, but the direct descriptor from this pH value remains base.
