How is conductivity measured?

A precise cell constant or K factor is given to a cell by comparison to a standard cell.

If ad.c.voltage is applied to the plates. Then polarisation and electrolysis will occur. This will cause bubbles to form on the plates.

To overcome this problem an a.c. voltage is applied to the plates which are also coated with a black platinised coating that will absorb the products of electrolysis on alternative half cycles.
