I took some phosphate buffer saline(7.4) into a beaker, included a Au electrode and reference electrode (Ag/AgCl) and tried to measure the potential using multimeter. The temperature and pressure is assumable same. The multimeter shows the potential some milivolts but the potential is decreasing like every 2-3 seconds. I thought if temparature and pressure is not changed much it should be fixed... can someone explain the reason of potential change...
