- Creating Pink Sterling Silver: Chemistry and Heat Treatment Explained
The discussion centers on methods to create a pink hue in sterling silver, exploring both chemical adjustments to the alloy and potential heat treatment techniques Participants consider the implications of alloy composition and surface treatments in achieving the desired coloration One participant inquires about altering the chemistry of sterling silver, which is typically 92 5% silver and 7
- Why Does the Pink Color in a Titration Fade Over Time?
The discussion revolves around the fading of the pink color produced by phenolphthalein during a titration over time Participants explore various chemical processes and factors that may contribute to this phenomenon, including equilibrium shifts, hydrolysis, and the absorption of carbon dioxide
- Understanding FTIR Peaks of PO4 Compounds • Physics Forums
The discussion focuses on the interpretation of FTIR (Fourier Transform Infrared Spectroscopy) peaks for PO4 (phosphate) compounds It establishes that multiple peaks at different wavelengths arise from various vibrational modes of the molecule, including stretching and bending vibrations Specifically, the modes v1, v3, and v4 correspond to distinct types of molecular vibrations, such as
- Why does a Walrus Blush? | Geophysical Institute
The skin of walruses becomes pallid when it is exposed to cold air or water and changes to pink when exposed to warmer ambient temperatures This color change may indicate that the circulatory output to the skin is altered to control their total body heat loss
- Exploration into the Physics of Rainbows
The simplest explanation of rainbow physics is based on internal reflections in the near-spherical shape of a raindrop
- Plasma Color: What Makes It Blue What Colors It Can Be?
Most of the plasma we see in everyday life is more or less blue (lightning, plasma lamps, static discharges through air etc etc) But if I understand correctly, plasma can be in many colors Like the plasma atmosphere of the sun, which as far as I know, is not blue What makes the usual plasma
