Answer:

A salt bridge or ion 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. If no salt bridge were present, the solution in one-half cell would accumulate a negative charge and the solution in the other half cell would accumulate a positive charge as the reaction proceeded, quickly preventing further reaction, and hence the production of electricity.[1]

Salt bridges usually come in two types: glass tubes and filter paper.

“The fight will go on,” said Captain Lakshmi Sehgal one day in 2006, sitting in her crowded Kanpur clinic where, at 92, she still saw patients every morning. She was speaking on camera to Singeli Agnew, a young filmmaker from the Graduate School of Journalism, Berkeley, who was making a documentary on her life.

Each stage of the life of this extraordinary Indian represented a new stage of her political evolution – as a young medical student drawn to the freedom struggle; as the leader of the all-woman Rani of Jhansi regiment of the Indian National Army; as a doctor, immediately after Independence, who restarted her medical practice in Kanpur amongst refugees and the most marginalised sections of society; and finally, in post-Independence India, her life as a member of the Communist Party of India (Marxist) and the All India Democratic Women’s Association (AIDWA), years that saw her in campaigns for political, economic and social justice.

“Freedom comes in three forms,” the diminutive doctor goes on to say on camera in her unadorned and direct manner. “The first is political emancipation from the conqueror, the second is economic [emancipation] and the third is social… India has only achieved the first.”

With Captain Lakshmi’s passing, India has lost an indefatigable fighter for the emancipations of which she spoke.

First rebellion

Lakshmi Sehgal was born Lakshmi Swaminadhan on October 24, 1914 in Madras to S. Swaminadhan, a talented lawyer, and A.V. Ammukutty, a social worker and freedom fighter (and who would later be a member of independent India’s Constituent Assembly).

Lakshmi would later recall her first rebellion as a child against the demeaning institution of caste in Kerala. From her grandmother’s house, she would often hear the calls and hollers from the surrounding jungles and hills, of the people who in her grandmother’s words were those “whose very shadows are polluting.” The young Lakshmi one day walked up to a young tribal girl, held her hand and led her to play. Lakshmi and her grandmother were furious with each other, but Lakshmi was the one triumphant.

After high school in Madras, she studied at the Madras Medical College, from where she took her MBBS in 1938. The intervening years saw Lakshmi and her family drawn into the ongoing freedom struggle. She saw the transformation of her mother from a Madras socialite to an ardent Congress supporter, who one day walked into her daughter’s room and took away all the child’s pretty dresses to burn in a bonfire of foreign goods. Looking back years later, Lakshmi would observe how in the South, the fight for political freedom was fought alongside the struggle for social reform. Campaigns for political independence were waged together with struggles for temple entry for Dalits and against child marriage and dowry. Her first introduction to communism was through Suhasini Nambiar, Sarojini Naidu’s sister, a radical who had spent many years in Germany. Another early influence was the first book on the communist movement she read, Edgar Snow’s Red Star over China.

Meeting Netaji

As a young doctor of 26, Lakshmi left for Singapore in 1940. Three years later she would meet Subhash Chandra Bose, a meeting that would change the course of her life
