Explanation / Answer

ANSWER:

Since HClO4 is a strong acid, it completely dissociates into ions as shown below

HClO4 ---> H+ + ClO4-

So, the concentration of the individual ions is equals to the concentration of the aqueous solution.

(i.e)  HClO4 ---> H+ + ClO4-

0.110 M 0.110 M 0.110 M

Therefore, 1) the concentration of H+ions = 0.110 M

2) The concentration of ClO4-ions = 0.110 M

3) The relationship between the concentration of H+ and OH- can be given as

[H+] * [OH-] = 1*10-14

  [OH-] = 1*10-14/[H+]

= 10 -14/0.110

Therefore, concentration of OH- ions = 9.09 * 10-14
