AI Thread Summary
The discussion centers on the impact of color change in a phenol solution when adsorbed by activated carbon on spectrometer readings. The original colorless solution turns pale yellow after contact with the adsorbent. The key concern is whether this color change will affect the spectrometer readings at the specified wavelength of 270 nm, which is used for measuring phenol concentration. It is important to consider how the presence of any colored compounds might interfere with the absorbance measurements, potentially leading to inaccurate results. Understanding the relationship between color and absorbance is crucial for ensuring reliable data in the thesis research.

i am conducting my thesis and i am adsorbing phenol with activated carbon, my original solution is clear(colorless) but when i cntact it with the adsorbent and filter it after a certain time, it became colored of some very pale yellow. i am just wondering will the color change have an effect on the reading on the spectrometer if my basis is 270 nm for the wavelength of phenol?

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...
I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
