Explain the pH change when the strong acid was added to the prepared buffer solution in relation to the pH of the buffer solution . Also indicate the change in the ph when the acid was mixed with the deionized water in relation to the deionized water ph. Based on the results obtained did the prepared buffer solutions resisit a ph change when minimal amounts of acid or base were mixed into the solution?
Under standard-state conditions, what spontaneous reaction will occur in aqeuous solution among the ions
