Question: 1 / 400

What is the effect of a solution with a pH above 7?

Acidic

Neutral

Alkaline

A solution with a pH above 7 is classified as alkaline, or basic. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate acidity, while values above 7 show an increase in alkalinity. Alkaline solutions have fewer hydrogen ions than neutral solutions, which typically leads to properties such as a slippery feel and the ability to neutralize acids. Common examples of alkaline substances include baking soda and soap.

In considering the context of the other options, substances labeled as acidic have a pH below 7, and those with a pH of exactly 7 are neutral. Corrosiveness, while it can be a property of certain alkaline solutions, is not solely indicative of a high pH level, as many acids are also corrosive. Thus, the defining characteristic of a solution with a pH above 7 is its alkalinity.
