Solution control
Testing is carried out by determining the Total Acidity of the bath as follows:
take 10 cc of the bath.
add a few drops of methyl orange indicator
titrate with N/10 NaOH solution until the color changes from red to yellow
The concentration of the bath can be determined from the number of cc used in the titration using the following table:
Power supply
Bath reconcentration must be carried out at a rate of 2 g/l of product for each point below the set value found during titration.
Precautions
Everything that comes into contact with the solution must be constructed from 316/L stainless steel or acid-resistant material.
