How does it relate to the concentration of hydroxide ion, OH (aq)? O The auto-ionization constant of water, Klw); pH 14 -(-loglOH- The acidic concentration of 1.0 M H30 laq): pH 14+ (og(OH- The auto-lonization constant of water, Kiwl: pH 14 +(-loglOH- @ The acidic concentration of 1.0 M H3O^.

Explanation / Answer

It iiss the auto-ionization of water.

H2O---> H+ + OH-

kW=[H+][OH-]=10^-14

For water [H+]=[OH-]=10^-7M

pH= - log [H+]. and pOH= - log[OH-]

Also pH+ pOH= 14

pH =14-pOH

= 14-(-log[OH-])

Therefore first option is correct.
