- When comparing pH, a solution with a pH of 5 contains 100 times the amount of H+ when compared to a solution with a pH of 7.Why can amino acids act as buffers in certain pH range? Refer to the structure of amino acids in your answer.The PH formula is given as PH=-log(H+). The H+ is the number of free ions of hydrogen. A seven PH is considered neutral. Discuss what having a low PH and a high PH means. What does a 12 PH mean? How about a 2? Which is more caustic? Is either a good thing at extremely high or low values? Explain fully as to what a PH means to you and what you use it for.
