At anode- oxidation will take place and Zn-s- will get oxidised to Zn2- leaving negatively charged electrons- making anode negatively charged- repelling negatively charged NO-x2212-3-

In the electrochemical cell shown above, which of the following half-reactions occurs at the anode?

${C u}^{2 +} + e \to {C u}^{-}$
$Z n (s) \to {Z n}^{2 +} + 2 e$
${Z n}^{2 +} + 2 e \to Z n (s)$
$C u (s) \to {C u}^{2 +} + 2 e$
${C u}^{2 +} + 2 e \to C u (s)$

At anode, oxidation will take place and $Z n (s)$ will get oxidised to $Z n^{2 +}$ leaving negatively charged electrons, making anode negatively charged, repelling negatively charged $N O_{3}^{-}$ .

In the electrochemical cell shown above, which of the following half-reactions occurs at the anode?Cu2++e→Cu−Zn(s)→Zn2++2eZn2++2e→Zn(s)Cu(s)→Cu2++2eCu2++2e→Cu(s)

At anode, oxidation will take place and Zn(s) will get oxidised to Zn2+ leaving negatively charged electrons, making anode negatively charged, repelling negatively charged NO−3.
