In summary, the pH of a citric acid solution at different concentrations varies depending on the concentration level. At lower concentrations, the pH tends to be more acidic, with a range of 1.5-2.5. As the concentration increases, the pH also increases, becoming more neutral at a concentration of 0.1M, with a pH of 6.04. At higher concentrations, the pH becomes more basic, with a range of 7.2-7.4 at a concentration of 1M. Overall, the pH of a citric acid solution can range from highly acidic to slightly basic depending on the concentration levels.
