What term describes a chemical that produces a basic substance, with a pH greater than 7?

Explanation:
pH above 7 means the substance is basic (alkaline). A base is a substance that creates a basic solution by accepting protons or by releasing hydroxide ions in water, which raises the pH. In general, bases push the solution into the basic range, while acids do the opposite and neutral substances sit around pH 7. An alkali is a base that dissolves in water to form hydroxide ions, but base is the broader term that fits any substance producing a basic environment. So the term that describes a chemical that produces a basic solution is base.
