For the strong acid solution 0.0058 m hclo4, determine [h3o+] and [oh−].

Q1) pH scale can be used to determine how acidic or basic a solution is.
Strong acids completely dissociate into hydronium ions, therefore the concentration of the acid is equal to the concentration of hydronium ions.
[HClO4] = [H3O+]
[H3O+] = 0.0058 M
Q2) pH can be calculated as follows,
pH = -log [H3O+]
pH = -log (0.0058)
pH = 2.24
By knowing the pH the pOH value can be found out
pH + pOH = 14
pOH = 14 -2.24 = 11.76
Knowing the pOH the hydroxide ion concentration can be calculated
pOH = -log[OH-]
[OH-] = antilog (-pOH)
[OH-] = 1.74 x 10^(-12)
Hydroxide ion concentration is = 1.74 x 10^(-12) M

Fine out you self hx
