To maintain the salt bridge, His31 will attempt to keep its proton as long as possible. When the salt bridge is disrupted, like in the mutant D70N, the pK a shifts back to a value of 6.9, much closer to that of His31 in the unfolded state. The difference in pK a can be quantified to reflect the salt bridge’s contribution to free energy.
In electrochemistry, a salt bridge or ion bridge is an essential laboratory device discovered over 100 years ago. [ 1 ] It contains an electrolyte solution, typically an inert solution, used to connect the oxidation and reduction half-cells of a galvanic cell (voltaic cell), a type of electrochemical cell .

The issue of salt losing its flavour is somewhat problematic. Salt itself, sodium chloride (NaCl), is extremely stable and cannot lose its flavour.France notes that Jesus was giving a lesson in moral philosophy and "not teaching chemistry"; to him, whether or not the proverbial image is factually accurate is of little relevance to the actual message of this verse.
