  • question_answer
    How many g of a dibasic acid (Mol. wt. = 200) should be present in 100 ml of its aqueous solution to give decinormal strength           

    A) 1 g

    B) 2 g

    C) 10 g

    D) 20 g

    Correct Answer: A

    Solution :

    [a] For Dibasic acid \[E=\frac{M}{2}=\frac{200}{2}=100\]
                \[N=\frac{W\times 1000}{E\times V(\text{in }ml)}\]
                            \[\frac{1}{10}=\frac{W\times 1000}{100\times 100}=W=1gm\].
