Question

Which of the following involves the reduction of copper? (A) Cu ( s )+1 / 2 O 2( g ) longrightarrow CuO ( s ) (B) Cu 2+( aq )+2 I ( aq ) longrightarrow 2 CuI ( aq ) (C) CuCI 2( s )+2 F -( aq ) longrightarrow CuF 2+ CI 2( g ) (D) CuO + H 2 O longrightarrow Cu ( OH )2

Tardigrade Admin · Accepted Answer

Correct answer is (b) Cu 2+( aq )+2 I ( aq ) longrightarrow 2 CuI ( aq )

Q. Which of the following involves the reduction of copper?

$C u (s) + 1/2 O_{2} (g) ⟶ C u O (s)$

$C u^{2 +} (a q) + 2 I (a q) ⟶ 2 C u I (a q)$

$C u C I_{2} (s) + 2 F^{-} (a q) ⟶ C u F_{2} + C I_{2} (g)$

$C u O + H_{2} O ⟶ C u (O H)_{2}$

Correct answer is (b) $C u^{2 +} (a q) + 2 I (a q) ⟶ 2 C u I (a q)$

Q. Which of the following involves the reduction of copper?

Cu(s)+1/2O2​(g)⟶CuO(s)

Cu2+(aq)+2I(aq)⟶2CuI(aq)

CuCI2​(s)+2F−(aq)⟶CuF2​+CI2​(g)

CuO+H2​O⟶Cu(OH)2​

Correct answer is (b) Cu2+(aq)+2I(aq)⟶2CuI(aq)

$C u (s) + 1/2 O_{2} (g) ⟶ C u O (s)$

$C u^{2 +} (a q) + 2 I (a q) ⟶ 2 C u I (a q)$

$C u C I_{2} (s) + 2 F^{-} (a q) ⟶ C u F_{2} + C I_{2} (g)$

$C u O + H_{2} O ⟶ C u (O H)_{2}$

Correct answer is (b) $C u^{2 +} (a q) + 2 I (a q) ⟶ 2 C u I (a q)$
