Standard reduction electrode potential at Zn 2+ / Zn is -0.76 V. This means

Question

Standard reduction electrode potential at Zn 2+ / Zn is -0.76 V. This means (A) ZnO is reduced to Zn by H 2 (B) Zn liberates H 2 with conc. Acids (C) Zn is generally the anode in an electrochemical cell (D) Zn is generally the cathode in an electrochemical cell

Correct answer is (c) Zn is generally the anode in an electrochemical cell

Q. Standard reduction electrode potential at $Z n^{2 +} / Z n$ is $- 0.76 V$ . This means

$Z n O$ is reduced to $Z n$ by $H_{2}$

$Z n$ liberates $H_{2}$ with conc. Acids

$Z n$ is generally the anode in an electrochemical cell

$Z n$ is generally the cathode in an electrochemical cell

Correct answer is (c) $Z n$ is generally the anode in an electrochemical cell

Q. Standard reduction electrode potential at Zn2+/Zn is −0.76V. This means

ZnO is reduced to Zn by H2​

Zn liberates H2​ with conc. Acids

Zn is generally the anode in an electrochemical cell

Zn is generally the cathode in an electrochemical cell
