The Argentometer—An Apparatus for Testing for Silver in a Fixing Bath
The Argentometer consists essentially of a light-source, a glass cell for holding the solution to be tested, a photronic cell, and a microammeter. The action of the instrument depends upon the change of transparency of a solution containing silver and hypo after the addition of sodium sulfiide and certain other chemicals. Formulas for the three solutions required and complete instructions for making a silver determination are given. Estimations can be made on hypo solutions containing either potassium or chrome alum and the results can be read directly from a scale upon the microammeter.
