SATHEE: Redox Reactions And Electrochemistry Ques 354

Redox Reactions And Electrochemistry Ques 354

Question: CuS is dissolved in dil. $H N O_{3}$ . Balanced equation with correct products is

Options:

A) $C u S = 2 H^{+} = 3 N {O^{-}}_{3} \to C u (N O_{3} + H_{2} S)$ $+ H_{2} O + N O_{2}$

B) $3 C u S = 8 H^{+} = 8 N {O^{-}}_{3} \to 3 C u {(N O_{3})}_{2} + 3 S$ $+ 4 H_{2} O + 2 N O$

C) $C u S + 4 N {O^{-}}_{3} \to C u {(N O_{3})}_{2} + H_{2} S + H_{2} O$

D) None of the above incorrect

Show Answer

Answer:

Correct Answer: B

Solution:

[b] $C u S$ (Black ppt.) on boiling with $H N O_{3}$ results in the formation of colloidal S and blue coloured solution of $C u {(N O_{3})}_{2}$ .
