- Why Does the Pink Color in a Titration Fade Over Time?
The pink color observed in titrations using phenolphthalein fades over time due to the absorption of carbon dioxide from the air, which forms carbonic acid and lowers the pH
- Creating Pink Sterling Silver: Chemistry and Heat Treatment Explained
The discussion centers on creating pink sterling silver, which is traditionally an alloy of 92 5% silver and 7 5% copper Altering the chemistry of the alloy to achieve a pink hue is challenging, as metals typically do not present in various colors Anodization using a caustic solution containing sulfur and a battery is suggested as a method to color silver Additionally, heating sterling
- Laptop screen flickering moving up and down with pink tint
This problem started around two hours ago while I was watching lectures on YouTube All of a sudden, the screen started flickering in and out of focus or moving up and down, with a pink shade appearing as soon as it goes out of focus moves up I tried Updating the NVIDIA drivers from 470 to 510
- 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
- Pink salmon — too much of a good thing? - Geophysical Institute
Pink salmon born in hatcheries, where professionals harvest eggs from wild salmon and rear them in captivity before releasing them in the ocean, have doubled in numbers since 1990 Russians have pink salmon hatcheries that increase numbers in the North Pacific and Bering Sea Alaskans run hatcheries in Valdez and other places in Prince William
- What do the blue and pink color of the rust indicator shown mean?
The discussion clarifies the meaning of blue and pink colors in a rust indicator composed of potassium hexacyanoferrate (III) and phenolphthalein The blue color indicates the presence of Fe2+ ions, confirming that rusting has already occurred
- 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
- Plasma Color: What Makes It Blue What Colors It Can Be?
The color of plasma is primarily determined by the type of gas used and its temperature Common gases and their corresponding plasma colors include CF4 (blue), SF6 (white blue), and H2 (pink) The blue glow observed in phenomena like lightning is attributed to the high temperatures, ranging from 18,000 to 54,000 degrees Fahrenheit, which produce black-body radiation Additionally, the color of
