Potentiometry formula

WebThe overall cell potential can be calculated using the formula given below. E c e l l = E i n d – E r e f + E s o l Where the potential drop between the indicator and reference electrodes over the electrolyte solution is given by … A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat. It works by sliding a conductor in a graphite disk that has a stable resistance depending on the position the conductor has on the disk.
