The unit of cell constant is_______
Answer: m-1 or cm-1
A conductor is an electrically conductive material that carries moveable electric charges. The mobile charged particles in metallic conductors, such as copper or aluminium, are electrons, though they can also be ions or other positively charged species in other circumstances.
A cell constant of conductor is defined as the ratio of the conductor’s length to the area of a cross-section of the conductor.
Cell constant is indicated by G*.
The formula is as follows;
G* = l/A …………………(1)
Here,
l = Unit of length
A = Area of cross section
The units of variables is as follows;
l = cm
A = cm2
Substitute in the formula (1)
G* = l/A
G* = cm/cm2 = cm-1
The cell constant is the ratio of the distance between conductance-titration electrodes to the area of electrodes, as estimated from the determined resistance of the specific conductance solution.
The cell constant is depends on the nature of conductor.
Therefore, The unit of cell constant is__cm-1_____
