of Cu is +0.34V while that of Zn is —0.76 V. Explain.
NEETprep Answer: value of Cu is positive because of the fact that sum of sublimation enthalpy and ionisation enthalpy to convert Cu(s) to (aq) is so high thatit is not compensatebyits hydration enthalpy. E° value for Zn is negative because of the fact that after removal of electrons from 4s orbital, stable 3 configuration is obtained,
