Answer:
Concentration of hydrogen ion is
[tex]1.671 * 10^{-10}[/tex]
Explanation:
pOH of solution [tex]= 4.223[/tex]
The concentration of OH ions is to be derived first
As we know-
pOH [tex]= - log [ OH^-][/tex]
Substituting the given values, we get -
[tex]4.223 = - log [OH^-]\\[/tex]
Taking antilog on both sides we get -
OH- concentration [tex]= \frac{1}{10^{4.223}}[/tex]
OH- concentration [tex]= 5.984 * 10^{-5}[/tex]
As we know tha
Pkw [tex]= P[H^+] + P[OH^-][/tex]
[tex]14 = P[H^+] + 4.223\\P[H^+] = 14 - 4.223\\P[H^+] = 9.777[/tex]
Concentration of hydrogen ion is
[tex]9.777 = - log{H^+]\\log{H^+] = -9.777\\{H^+] = \frac{1}{10^{-9.777}} \\{H^+] = 1.671 * 10^{-10}[/tex]
Concentration of hydrogen ion is
[tex]1.671 * 10^{-10}[/tex]
