Question

Which of the following statements is/are correct about $6.8\%$ strength of $H_2{O}_2$?

• A. Its normality is $4N$.
• B. Its molarity is $2M$.
• C. Its volume strength is $22.4V$.
• D. Its volume strength is $11.2M$.

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A Its normality is $4N$.
B Its volume strength is $11.2M$.
C Its volume strength is $22.4V$.
D Its molarity is $2M$.

a. $1.7\%=1N$
$6.8\%=4N$
b. $M=\frac{4N}{2}=2M$
c. $1.7\%={5.6}^{\prime }{V}^{\prime }$
$6.8\%={22.4}^{\prime }{V}^{\prime }$
d. Volume strength $=5.6\times N=5.6\times 2\times M=11.2\times M$
Hence options A,B,C & D are correct.
