Aurora Forecast - Geophysical Institute
4 天之前 · The aurora is most often seen as a striking green, but it also occasionally shows off other colors, ranging from red to pink or blue to purple. Oxygen at about 60 miles up gives off the familiar green-yellow color, while oxygen at higher altitudes (about 200 miles above Earth’s surface) gives all-red auroras.
Why Does the Pink Color in a Titration Fade Over Time? - Physics …
2005年1月31日 · In summary, the pink color obtained from the 2-3 phenolphthalein indicator at the end point of the titration gradually disappears over time due to the absorption of CO2 from the air, which produces the weak acid HCOOOH. This results in a drop in pH and the color of phenolphthalein is dependent on the pH of the solution.
