Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (a metal or a semiconductor) and an ionic conductor (the electrolyte), and which involve electron transfer between the electrode and the electrolyte or species in solution. Solutions solutions are just mixtures where two or more substances are well mixed (homogeneous) we are used to thinking of liquid solutions where a solid substance (the solute) is dissolved in a liquid substance (the solvent) but liquids can be dissolved in other liquids, and solids can be dissolved in solids, and gases can be dissolved in.
