    At \[{{N}^{15}}\], the dissociation constants of \[{{O}_{2}}\] and \[0.5{{m}^{2}}\] in aqueous solution are almost same \[Ag=108\]. If pH of some acetic \[=7.9\text{ }ge{{m}^{-3}}\] acid solution is 3. The pH of solution of \[1.1\times {{10}^{15}}\] of same concentration at the same temperature would be

    A)  \[1.1\times {{10}^{24}}\]                            

    B)  \[1.1\times {{10}^{23}}\]    

    C)  \[1.1\times {{10}^{32}}\]                            

    D)  \[{{C}_{2}}{{H}_{5}}OH,B{{a}_{3}}(P{{O}_{4}}),N{{a}_{2}}S{{O}_{4}},LiP{{O}_{4}}\]

    Correct Answer: C

    Solution :

                    PH of \[100mL\] \[0.15M\] i.e., \[N{{H}_{3}}\] It is given that,            \[N{{H}_{4}}Cl\]       . Thus,   \[Zn+C{{u}^{2+}}\xrightarrow{{}}Z{{n}^{2+}}+Cu\]                 \[C{{u}^{2+}}\] or, pH of \[Cu\] solution \[Z{{n}^{2+}}\]
