Variables Used
Concentration at given time - Concentration at given time is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration is usually expressed in terms of mass per unit volume.
Maximum Diffusion Current - Maximum Diffusion Current is the maximum current that passes through a cell when the concentration of electro-active species at the electrode surface is zero.
Diffusion Constant - Diffusion Constant also known as the diffusion coefficient or diffusivity, is a physical constant that measures the rate of material transport.
Rate of Flow of Mercury - Rate of Flow of Mercury the volume of mercury that passes through a cross-section each second.
Drop Time - Drop Time is the time during when triangular impact pressure decreases from the highest to the lowest.
Moles of Analyte - Moles of Analyte the quantity of an analyte in a sample that can be expressed in terms of moles.
