Question

What is the pH of a 2.6 M solution of HClO4?

Answer 1

oh its been awhile. umm I know the pH=[H] so maybe do a ICE table and go from there

Answer 2

First thing you need to do is establish whether or not you are dealing with a strong or weal acid...How do you do that?

Answer 3

HClO4 is a strong acid so it dissociates completely.

HClO4 --> H+ + (ClO4)-

ph= -log[H+]
ph= -log[2.6M]
ph= -0.41497334797
