A solution with a pH close to 1 would be classified as?

A solution with a pH close to 1 is classified as acidic because the pH scale ranges from 0 to 14, where lower values indicate increasing acidity. A pH of 7 is considered neutral, as it is the midpoint of the scale where neither acidic nor basic characteristics are present. Values below 7 signify acidity, with a pH of 1 demonstrating a strong acid presence, indicating that the concentration of hydrogen ions (H⁺) is high. Conversely, a basic solution would have a pH above 7, reflecting a lower concentration of hydrogen ions and a higher concentration of hydroxide ions (OH⁻). The term "isotonic," meanwhile, refers to solutions with equal concentrations of solutes, which is unrelated to the pH classification. Thus, a pH close to 1 unmistakably classifies the solution as acidic.
