what is the ph if 1ml of 0.1m hcl is added to 99ml of pure water?
now if instead of pure water a buffer is used: hpo4-2/h2po4- pka = 7.2 assume the initial ph of this buffer is 7 (like the pure water example). -first you must you must use the henderson-hasselbalch equation to determine the ratio of hpo4-2/h2po4- , which is 0.063m to .1m. using the same amount of hcl added (.001m), determine the change in ph that occurs to the buffer when the hcl is added.
(i already answered the first part, i just need the second part. show and explain your work ! )
