Question

How many grams of a dibasic acid (Mol. Wt. =200) should be present in 100 ml of its aqueous solution to give decinormal strength
A. (a)1 g
B. (b)2 g
C. (c )10 g
D. (d)20 g

Answer 1

Correct Answer - A
For Dibasic acid `E=M/2=200/2=100`
`N=(Wxx1000)/(ExxV("in ml"))`
`1/10=(Wxx1000)/(100xx100)=W =1 g`
