Why is the pH of the medium important for the formation of chelated complexes between metal ions and ligands? Choose the best answer: Select one: a. Because the ligands give rise to acid-base reactions that influence the stability of the chelate b. Because if the pH is not very acidic, the ligands do not protonate and the complex cannot form c. Because the pH of the medium is always important for any type of reaction. d. Because in the absence of pH there is no reaction of any kind
