A solution with pH less than 7 is described as...

• A. Neutral
• B. Basic
• C. Acidic
• D. Alkaline

Answer: (C)

pH measures how acidic or basic a solution is by looking at hydrogen ion concentration. A lower pH means more hydrogen ions. When the pH is below 7, the solution has a higher concentration of H+ than pure water, so it is described as acidic. Neutral solutions sit at pH 7, with equal H+ and OH−, while basic (alkaline) solutions have pH above 7. So a solution with pH less than 7 is best described as acidic. For context, lemon juice or stomach acid are common examples of acidic solutions.
