47. Which of the following statement(s) is/are correct when a mixture of $NaCl$ and $K _2 Cr _2 O _7$ is gently warmed with conc. $H _2 SO _4$ ?
$(1998,2 M)$
(a) A deep red vapours is formed
(b) Vapours when passed into $NaOH$ solution gives a yellow solution of $Na _2 CrO _4$
(c) Chlorine gas is evolved
(d) Chromyl chloride is formed
Show Answer
Answer:
Correct Answer: 47. $(a, b, d)$
Solution:
$4 NaCl+K _2 Cr _2 O _7+6 H _2 SO _4 \longrightarrow \underset{\text { Chromyl chloride (red vapour)}}{2 CrO _2 Cl _2}$
$\hspace{60mm}+4 NaHSO _4+2 KHSO _4+3 H _2 O$
$CrO _2 Cl _2+4 NaOH \longrightarrow \underset{\text{Yellow solution}}{Na _2 CrO _4}+2 NaCl+2 H _2 O$
