Question

relation between hydration enthalpy and electrode potential

Answer 1

Hey mate,

★ In one sentence - Electrode potential is inversely proportional to hydration enthalpy.

★ Explanation-
- Hydration enthalpy is nothing but the heat energy released when new bonds are made between the ions and water molecules.
- Higher the hydration enthalpy, more easy for metal to lose electron.
- This causes them to have more negative electrode potential and act as strong reducing agents (like lithium)
- Similarly, low hydration enthalpy causes high positive electrode potential acting as strong oxidizing agents.


Hope this helps...
