Polarization may be best prevented by supplying achemical which is rich in oxygen and at the same time parts with it this reason, we add to the acid solution bichromate of potash, and in THE GUIDE 21 the alkali cells we mix with the carbon, when it is moulded, powdered bin-oxide of maganese. By these means the excess of (H) liydrogen is takencare of as fast as it is liberated and the cell will not become polarized. What is amalgamation?
