Two voltameters one of copper and another of silver, are joined in parallel. When a total charge q flows through the voltameters, equal amount of metals are deposited. If the electrochemical equivalents of copper and silver are z 1 and z 2 respectively the charge which flows through the silver voltameter is 171 views.

The ampere joined the si units for distance, time and mass, which had been incorporated since the time of the 1875 treaty of the meter. But scientists were already finding that the silver voltameter-based definition of the unit for current was no longer accurate enough.
The first method for lead analysis was ba sed on the separation of silver from lead during the metallurgical process, cupellation. By the roman empire knowledge about the oxidation and reduction potentials of lead with respect to the known metals was codified within the days of the week.
From the edax studies, it was observed that nanocomposite coatings of desired stoichiometry can be synthesized using present coating technique. The cyclic voltametric techniques such as tafel analysis and electrochemical impedance spectroscopy (eis) analysis were conducted to study the anticorrosion properties of the coatings.

Two voltameters, one of copper and another of silver, are joined in paralleled. When a total charge q flows through the voltameters, equal amount of metals are deposited. If the electrochemical equivalents of copper and silver are z1 and z2 respectively, the charge which flows through the silver voltameter is? q/ (1+z1/z2).

The voltameter is an electrolytic cell and the measurement is made by weighing the element deposited or released at the cathode in a specified time. It consists of two silver plates in a solution of silver nitrate. When current is flowing, silver dissolves at the anode and is deposited at the cathode. The cathode is initially massed, current is passed for a measured time and the cathode is massed again.
Cyclic voltammetry is a sophisticated potentiometric and voltammetric method. During a scan, the chemical either loses an electron (oxidation) or gains an electron (reduction) depending on the direction of the ramping potential.
The occurrence of gold mineral is composed of native gold, electrum, native silver, iron-bearing native silver, goldcuprid and acanthite.

Cyclic voltammetry (cv) has become an important and widely used electroanalytical technique in many areas of chemistry. It is often used to study a variety of redox processes, to determine the stability of reaction products, the presence of intermediates in redox reactions, electron transfer kinetics, and the reversibility of a reaction.
