Faraday has developed a plating process to make high-performance chrome coatings
Faraday has developed a plating process to make high-performance chrome coatings from trivalent chromium instead of highly toxic hexavalent chromium. This is an application of:
- A. Green revolution
- B. Green chemistry
- C. waste management
- D. revolution resource recovery
Step-by-step solution
Green chemistry focuses on designing chemical processes that minimize or eliminate the use of hazardous substances. Replacing toxic hexavalent chromium with the safer trivalent chromium in plating aligns with green chemistry principles. The other options (green revolution, waste management, revolution resource recovery) are not directly related to reducing toxicity in chemical processes.
