thomaster (thomaster):
pH = -log[H+] You have 2 moles of H+ So -log(2) = 3.40
thomaster (thomaster):
HClO4 is a strong acid so it dissociates completely
OpenStudy (anonymous):
-log(2) doesn't equal 3.4....it equals -.301
thomaster (thomaster):
wow, 1 year later. But you're right. No idea why I said 3.40 xD Probably entered something wrong in my calc at that time.
