Titrants
JSA supplies a complete line of laboratory reagents including titrants for determining the concentrations of all metal finishing process solutions.
- Options include standardized acids and bases, oxidation-reduction, non-aqueous and general titrants
- Most common titrants are in stock and ready to ship (Example – 1.0N Hydrochloric Acid, 1.0N Sodium Hydroxide, 0.0575 EDTA)
- Titrants are certified traceable to NIST and all come with expiration dates and certificates of analysis
- Packaging sizes range from 120 ml to 55 gallon drum
- Need a non-standard titrant? Custom formulations available upon request

Description
Titrating metal finishing process solutions regularly will help maintain optimum chemical performance, reduce rejects and maximize productivity. How often should you titrate? Factors include:
- Tank Size – chemistry in smaller tanks may change more rapidly
- Production Volume – high production will deplete the chemistry more rapidly
- Drag-Out – pay attention to large rack parts and plating barrels with high drag-out volumes that dilute the solution
- Temperature – high temperature solutions evaporate quickly which changes the chemical concentration
- Chemical Process – some chemistries change more rapidly than others (Example – electroless nickel plates out of solution and with high volumes of parts it may be necessary to titrate the nickel after every load)
- Time – sometimes it is hard to find the time to titrate, but it takes more time to fix problems and re-run parts
Important things to keep in mind when titrating:
- Check the expiration date on your titrants and reagents
- Make sure to use the correct titrant molarity or normality
- Use volumetric pipets to ensure accuracy
- Make sure to use clean glassware
- Put a piece of white paper under the flask to help see the color change
- If you are not sure you have reached the endpoint, record the volume on the buret and add a few more drops to see if the color changes
- Always clean pipets, flasks and burets after use
