According to Faraday's Law, what does Wt = KIT = kg represent?

The equation Wt = KIT = kg describes the quantitative relationship between the weight of material deposited or dissolved during an electrochemical reaction and the key parameters of the process, specifically the current and time. In this context, Wt refers to the weight of the substance, K is a constant (often referred to as Faraday's constant), I is the current flowing through the electrochemical cell, and T is the time for which the current flows.

This relationship arises from Faraday's Law, which states that the amount of substance transformed in an electrochemical reaction is directly proportional to the quantity of electric charge passed through the system. Thus, the equation captures how the current and time together determine the mass of the substance involved, emphasizing the role of these variables in the electrochemical process.

The other options do not relate directly to this specific equation; for instance, resistance is not represented or calculated in this form, and the concepts of voltage differentials and electron flow, while relevant to electrochemistry, do not directly pertain to the weight calculation of material as expressed by the equation.
