Question

When a copper wire is placed in a solution of AgNO3, the solution acquires blue colour. This is due to the formation of (A) Soluble complex of copper with AgNO3 (B) Cu+ ions (C) Cu2+ ions (D) Cu- ion by the reduction of Cu

Tardigrade Admin · Accepted Answer

Since, Ag+ ions are reduced to Ag and E°Ag+/Ag>E°Cu++/Cu Cu is oxidized to Cu++.

Q. When a copper wire is placed in a solution of $A g N O_{3}$ , the solution acquires blue colour. This is due to the formation of

Soluble complex of copper with $A g N O_{3}$

$C u^{+}$ ions

$C u^{2 +}$ ions

$C u^{-}$ ion by the reduction of $C u$

Since, $A g^{+}$ ions are reduced to Ag and
$E_{A g^{+} / A g}^{\circ} > E_{C u^{++} / C u}^{\circ}$ $C u$ is oxidized to $C u^{++}$ .

Q. When a copper wire is placed in a solution of AgNO3​, the solution acquires blue colour. This is due to the formation of

Soluble complex of copper with AgNO3​

Cu+ ions

Cu2+ ions

Cu− ion by the reduction of Cu
