SUMMARY

The forum discussion centers on the challenges of removing silver nitrate stains from skin, particularly after its use in laboratory settings. Users share various methods, including washing with salt water, using sodium thiosulfate, and the ineffectiveness of bleach or scrubbing. It is established that silver nitrate can cause long-lasting skin discoloration, which typically fades after a week. The conversation also touches on safety precautions, emphasizing the importance of using gloves when handling silver nitrate due to its potential to irritate skin and cause staining.

PREREQUISITES
  • Understanding of silver nitrate's chemical properties and uses
  • Familiarity with laboratory safety protocols
  • Knowledge of skin chemistry and healing processes
  • Experience with photographic chemicals and their applications
NEXT STEPS
  • Research the use of sodium thiosulfate as a photographic fixer and its effectiveness in removing silver stains
  • Learn about the long-term effects of silver nitrate exposure on skin
  • Investigate alternative methods for stain removal from skin and surfaces
  • Explore safety measures and personal protective equipment (PPE) for handling hazardous chemicals in laboratories
USEFUL FOR

Laboratory technicians, chemistry students, and anyone involved in photography or medical applications using silver nitrate would benefit from this discussion.

You ever seen that tarnish-x stuff? Would that have any effect?

Nah I think it's chemically bonded with your skin so you'd have to use an organic acid, and that I wouldn't recommend.

soak affected area in sodium thiosulfate? It should then form soluble silver complexes that can be washed away. labeled as photographic fixer in stores
