  • question_answer
    A compound whose aqueous solution will have the highest \[pH\] [CPMT 1974, 75, 78; MP PET 1996; DPMT 1982, 83]

    A)                 \[NaCl\]              

    B)                 \[N{{a}_{2}}C{{O}_{3}}\]

    C)                 \[N{{H}_{4}}Cl\]               

    D)                 \[NaHC{{O}_{3}}\]

    Correct Answer: B

    Solution :

                    \[N{{a}_{2}}C{{O}_{3}}\] when react with water form strong base and weak acid. So its aqueous solution is basic.
