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

Answer

(a) False (b) False (C ) True

Explanation

`K_(2)Cr_(2)O_(7)+2C(charcoal)undersettoDelta Cr_(2)+K_(2)CO_(3)+COuparrow`.
`2KMnO_(4)+5H_(2)undersettoDelta2KOH+2MnO+4H_(2)O`
`FeCl_(3).6H_(2)O+6-CHunderset(OCH_(3))underset(|)overset(OCH_(3))overset(|)(C)-CH_(3) to ("anhydrous")+12CH_(3)OH+6CH_(3)COOH_(3)`.
