Explanation / Answer

[H3O+] = 8.6 * 10^ -6 M We know that pH = - log [ H3O + ]                            = - log 8.6 * 10^ -6                            = 6 - log 8.6                            = 5.06 If pH ,& , it is acidic in nature & pH > 7 ,it is basic in nature. Since pH = 5.06 -------- acidic pOH = 14 - pH = 8.94 [OH-] = 10 - pOH = 1.148 * 10^-9 M pH = - log [ H3O + ]       = - log 2.4 * 10^ -8      = 8- log 2.4     = 7.6   --------- basic pOH = 14 - pH = 6.4 [OH-] = 10 - pOH = 3.98 * 10^-7 M      = 8- log 2.4     = 7.6   --------- basic pOH = 14 - pH = 6.4 [OH-] = 10 - pOH = 3.98 * 10^-7 M pOH = 14 - pH = 6.4 [OH-] = 10 - pOH = 3.98 * 10^-7 M
