When a copper wire is immersed in a solution of ${\rm{AgN}}{{\rm{O}}_3}$ , the colour of the solution becomes blue because copper :

Is oxidised to ${\rm{C}}{{\rm{u}}^{2 + }}$

Forms a soluble complex with ${\rm{AgN}}{{\rm{O}}_3}$

Is reduced to ${\rm{C}}{{\rm{u}}^{2 - }}$

Splits up into atomic form and dissolves

When a copper wire is immersed in a solution of

\mathrm{AgN}{\mathrm{O}_3}

, the colour of the solution becomes blue because copper :

View answer and explanation

Correct option: B

Is oxidised to

\mathrm{C}{\mathrm{u}^{2 + }}

Option B (Is oxidised to

\mathrm{C}{\mathrm{u}^{2 + }}

) is correct because copper loses electrons and forms copper(II) ions, which give the solution a blue color.
