Redox Reactions And Electrochemistry Ques 440

Question: The oxidation number and the electronic configuration of sulphur in $H_{2} S O_{4}$ is [KCET 2002]

Options:

A) + 4; $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2}$

B) + 2; $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{2}$

C) + 3; $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{1}$

D) + 6; $1 s^{2} 2 s^{2} 2 p^{6}$

Show Answer

Answer:

Correct Answer: D

Solution:

$H_{2} \overset{*}{S O_{4}},$ $2 \times (+ 1) + x + 4 \times (- 2) = 0$ $+ 2 + x - 8 = 0$ ; $x = 8 - 2 = + 6$ Electronic configuration of sulphur in $H_{2} S O_{4}$ is $1 s^{2}, 2 s^{2}, 2 p^{6}$ .
