A) 11.2
B) 5.6
C) 1.7
D) 3.4
Correct Answer: D
Solution :
[d] \[{{H}_{2}}{{O}_{2}}\equiv KI\equiv {{I}_{2}}\] \[mEq\,of\,{{H}_{2}}{{O}_{2}}=5\times N\] \[mEq\,of\,{{I}_{2}}=\frac{Weight}{E.w}\times 1000\] \[\frac{1.27}{127}\times 1000=10\,mEq\] \[{{I}_{2}}=M.w=254\] \[E.w=\frac{M.w}{2}=\frac{254}{2}=127\] \[\therefore mEq\,of\,{{H}_{2}}{{O}_{2}}=mEq\,of\,{{I}_{2}}\] \[5\times N=10\] \[\therefore N=2\] 1 N of \[{{H}_{2}}{{O}_{2}}=1/7\]% of \[{{H}_{2}}{{O}_{2}}\] 2 N of \[{{H}_{2}}{{O}_{2}}\] = 3.4% \[{{H}_{2}}{{O}_{2}}\]
