This provides a means of eliminating 'liquid junction potential' between two half cells. It was indicated laconically without any experimental details (https://en.wikipedia.org/wiki/Salt_bridge#cite_ref-1) that the salt bridges can also be made using laboratory filter paper soaking in a suitable inert salt solution. In this article we have made a detailed potentiometric experimental study on four representative titrations viz. strong acid (HCl) versus strong base (NaOH), weak acid (CH3COOH) versus strong base (NaOH), ferrous iron (Fe2+) versus dichromate (Cr2O72-), and chloride ion (Cl-) versus silver ion (Ag+) using filter paper salt bridge and compared the results with those obtained using Agar-Agar salt bridge. http://pubs.sciepub.com/wjce/4/6/1/wjce-4-6-1.pdf salt bridge Filter paper salt bridge Potentionmetric titrations
