Development of potensiometry method for Zn analysis

In this research, focus for analysis Zn ion using a concentration cell potentiometry method with a Hantexmultimeter. Concentration cells are electrochemical cell circuits where the same type of solution is used but different concentrations, the more concentrated solution being the more dilute cathode and solution to the anode. So that the flow of electrons from the dilutes solution to concentrated occurs until equilibrium is reached. The multimeter connected with computer to display data processing so the analysis be easier. This method has high accuracy 98.20% and precision 0.45%.This potentiometry method can be used as an alternative method of Zn analysis. (paper)
