Salt Bridge can be understood as a junction connecting the anode and the cathode compartment in an electrolytic solution. It is used in electrochemical cells for connecting the oxidation and reduction half cells where a weak electrolyte is used. It is responsible for maintaining electrical neutrality in the two-compartment of the Daniell cell. Salt Bridge is a glass tube consisting of ammonium nitrate or potassium chloride in gelatin form. Originates from external sources such as a battery The cathode is negative.Įlectrical energies are caused by internal Chemical reactions.Īn external source is required for the production of Chemical reactions. The cathode is the positively charged part. The following table discusses the differences at a glance:Įlectricity can be produced with the help of chemical reactions.Įlectric currents are used for chemical reaction transmission.Ĭonverts chemical energy into electrical ones and vice-versa.Įlectrical energy gets transformed into chemical energy. Daniell cell can be represented as Zn | Zn 2+(aq) | | Cu 2+(aq) | Cu where the “| |” represents the salt bridge, the left side symbolizes oxidation process, and the right one pertains to the reduction of half-cell.ĭifference between Daniell Cell and Electrolytic CellĮlectrochemical cells can be divided into two main types:.The salt bridge completes the entire circuit. Electricity is produced as a result of this particular flow in the opposite direction of the electrons travelling from cathode to anode. The electrons released by the zinc at the anode reach the cathode through an interconnecting metal wire. ![]()
