Sodium halides are heated separately with concentrated H2SO4. Select the correct statement(s).

NaCl gives HCl, and no Cl2 is formed because HCl is not oxidised by the acid

NaBr gives HBr, which is partly oxidised to Br2 with SO2 as a reduction product

NaI gives I2 along with sulphur-containing reduction products such as H2S

Sodium halides are heated separately with concentrated $H X_{2} SO X_{4}$ . Select the correct statement(s).

ANaCl gives $HCl$ , and no $Cl X_{2}$ is formed because $HCl$ is not oxidised by the acid
BNaBr gives $HBr$ , which is partly oxidised to $Br X_{2}$ with $SO X_{2}$ as a reduction product
CNaI gives $I X_{2}$ along with sulphur-containing reduction products such as $H X_{2} S$
DNaF gives $F X_{2}$ because the acid oxidises $F X^{-}$

The reducing power of

HX

rises from

HCl

HI

HCl

is not oxidised,

HBr

gives

Br X_{2}

and

SO X_{2}

, and

HI

gives

I X_{2}

and

H X_{2} S

. Fluoride cannot be oxidised by

H X_{2} SO X_{4}

(

E^{\circ} (F X_{2} / F X^{-}) = 2.87 V

), so NaF only gives

HF

. Options 1, 2 and 3 are correct.
