How do you calculate the cell constant for a flow-through resistivity cell (liqiud flows through a tube) with two electrode rings parallel to each other?
Homework Answers
Cell constant = (distance between electrode)/(cross sectional area)
Cell constant is a specific value for a conductivity cell.
Conductivity = conductance × cell constant
Usually wheatstones bridge is used to measure conductivity of a cell. The cell constant we have to determine first through this expression.

In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...
