Which type of electrolytic are used in salt bridge?
Which type of electrolytic are used in salt bridge?
Only those electrolytes for which cations and anions have nearly the same ionic mobilities (i.e. distance traveled by an ion per second under a potential gradient of one voltmeter) are used as electrolytes in the salt bridge. Thus KCl, KNO3, K4SO4, and NH4NO3 are preferred over NaCl, NaNO3 and Na2SO4.
