A. 4.2 V is the voltage of a galvanic cell made with magnesium (Mg) and gold(Au).
What is the voltage of a galvanic cell made with magnesium?
The bigger the reduction ability, the more likely the steel is to be reduced and act as the oxidizing agent. Returning to the copper-magnesium galvanic cellular, the same old electrode potential of copper is 0.337 volts, whilst the standard electrode capability of magnesium is -2.370 volts.
Cell voltage is also known as cell ability (E) and electromotive force (emf). the electrical voltage or ability is measured in volts (V). The volt is related to strong values, joules (J), and electric powered fee, coulomb (C). The connection between these is defined with the equation: 1J=1C×1V.
