Final answer:
A solution with a pH of 12.0 is basic.
Step-by-step explanation:
A solution with a pH of 12.0 is considered basic. pH is a measurement of the acidity or basicity of a solution, with values ranging from 0 to 14. A solution with a pH less than 7 is acidic, a solution with a pH greater than 7 is basic, and a solution with a pH of 7 is considered neutral.
