Among the following statement choose the true or false statements(s).
A) `K_(2)Cr_(2)O_(7)` on heating with charcoal gives metallic potassium and `Cr_(2)O_(3)`
B) On heating in current of `H_(2)` the crystalline `KMnO_(4)` is converted into `KOH` and `Mn_(3)O_(4)`
C) Hydrated ferric chloride on treatment with `2-2`-dimethoxypropane gives anhydrous ferric chloride.

Text Solution

Verified by Experts

The correct Answer is:
(a). False
(b) False
(c) True
(a). `K_(2)Cr_(2)O_(7)++2C("charcoal")overset(Delta)toCr_(2)O_(3)+K_(2)CO_(3)+Couarr`
(b). `2KMnO_(4)+5H_(2)overset(Delta)to2KOH+2MnO+4H_(2)O`
(c). `FeCl_(3)+6H_(2)O+6CH_(3)-underset(OCH_(3))underset(|)overset(OCH_(3))overset(|)(C)-CH_(3)toFeCl_(3)("anhydrous")+12CH_(3)OH+6CH_(3)COCH_(3)`.
