A solution with a pH value of more than 7 is called _____.
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Basic
The pH scale (0 to 14) measures how acidic or basic a solution is, from the concentration of hydrogen ions in it. pH 7 is neutral (pure water), a pH below 7 is acidic, and a pH above 7 is basic (alkaline). Soap solution, baking soda solution and lime water are basic, with pH above 7.
