Some Basic Concepts Of Chemistry Question 110

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

Options:

A) 1 g

B) 2 g

C) 10 g

D) 20 g

Show Answer

Answer:

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 $ .
