hey student..
Leaching is the loss or extraction of certain materials from a carrier into a liquid (usually, but not always a solvent). Specifically, it may refer to:
the process of extracting minerals from a solid by dissolving them in a liquid
Ellingham diagrams are a particular graphical form of the principle that the thermodynamic feasibility of a reaction depends on the sign of ΔG, the Gibbs free energy change, which is equal to ΔH − TΔS, where ΔH is the enthalpy change and ΔS is the entropy change.Simple Ellingham diagram for high temperature (0°C – 2500°C) oxidation of several metals and carbon
The Ellingham diagram plots the Gibbs free energy change (ΔG) for each oxidation reaction as a function of temperature.
