`KMnO_4` reacts with `Na_2S_2O_3` in acidic, strongly basic and aqueous (neutral) media. `100mL` of `LMnO_4` reacts with 100 mL of 0.1 M `Na_2S_2O_3` in acidic, basic and neutral media. Q. The molarity (M) of `KMnO_4` solution in basic medium is:A. 0.8 MB. 0.08 MC. 0.26 MD. 0.026 M |
Answer» Correct Answer - A `MnO^(4)^(ɵ)-=S_(2)O_(3)^(2-)(S_(2)O_(3)^(2-)to2SO_(4)^(2-)+8e^(-))(n=8)` `100 mLxxN-=100mLxx0.1xx8` `N=0.8` `M=(N)/("n factor")=0.8M` |
