The mineral element that is present in a bridge ( salt bridge ) is ; Potassium
Bridge ( salt bridge ) in electrochemistry is a device ( laboratory ) that connects the two halves of a galvanic cell in order to maintain the electrical neutrality within the cell.
Salt bridges are made of inert salts in order to maintain the electrical neutrality within the galvanic cell. an example of an inert salt that can be used to make this bridge is KCl or KNO₃
Hence we can conclude that the mineral element present in a salt bridge is Potassium.
