Some Basic Concepts Of Chemistry Question 226
Question: How many g of a dibasic acid (Mol. wt. = 200) should be present in 100 ml of its aqueous solution to give decinormal strength [AIIMS 1992]
Options:
A) 1 g
B) 2 g
C) 10 g
D) 20 g
Show Answer
Answer:
Correct Answer: A
Solution:
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 $ .
