salt bridge

A salt bridge, in electrochemistry, is a laboratory device used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell. It maintains electrical neutrality within the internal circuit, preventing the cell from rapidly running its reaction to equilibrium. If no salt bridge were present, the solution in one half cell would accumulate negative charge and the solution in the other half cell would accumulate positive charge as the reaction proceeded, quickly preventing further reaction, and hence production of electricity.

Salt Bridge is a Hindi language film directed and produced by Abhijit Deonath. It depicts the story of an Indian man and his relationship with an Australian woman, which constantly faces hurdles owing to the cultural differences. The film premiered at the All Lights India International Film Festival held in Kochi, Kerala, India this December.
