Ligand. – the anion or neutral molecule that combines with a cation to form a complex. Can be various species. E.g., H. The pores can be sealed (closed-cell foam), or they can form an interconnected network (open-cell foam).. The defining characteristic of metal foams is a very high porosity: typically 75-95% of the volume consists of void spaces.. Electrolysis is a fairly simple process. . There are two plates in a solution, and an electric current is sent through.. The plates are the cathode, where reduction takes place, and the anode, where oxidation takes place.. Adil. Hamid.
