Arrhenius Theory
Arrhenius theory gives the peoperties of an electrolyte in solution.The main postulates are given below:-
1)When any electrolyte is dessolved in water or in any polar solvent,electrolyte dissociates giving electrically charged particles called ions.Positively charged is called cation while negatively charged is called anion.
2)In solution,after dissociation,ions tend to reunite.Thus an equillibrium state occurs between electrolyte and ions.It is called dynamic equllibrium and described by equillibrium constant.
3)In solution state,cation equels to anion.So it is electrically neutral.
4)On passing electric current,charged particles are attracted towards opposite electrods thus conducting electricity.
5)The properties of electrolyte in solution is due to ions present...etc.

Discovery Of Protons
Protons are subatomic particles that, with neutrons and electrons, are the principal constituents of atoms. Protons are positively charged atoms that reside in the nucleus of an atom. These protons add the overall positive charge of a molecule. The mass...
