How to extract sulfur from ground water

AI Thread Summary
Boiling ground water containing sulfur can produce a yellow sulfur residue, but this does not guarantee the presence of sulfur. The bad odor associated with the water is likely due to hydrogen sulfide and other sulfur compounds. Boiling can oxidize sulfides to elemental sulfur, but this method is not effective for purifying water for drinking. Hydrogen sulfide tends to boil off and condense with the water, complicating the extraction process. Understanding sulfur chemistry is essential for accurate results in such experiments.

Will boiling ground water that contains sulfur produce a yellow sulfur residue.

Thanks,

It can. This doesn't mean that a yellow residue implies sulfur.
 
The ground water had a bad odor and I was told that it was produced from sulfur in the water. I guess the question is weather the sulfur boils away with the water and, if not, how much water would need to be boiled away to produce a noticeable amount of sulfur. My son had this question at school and the teacher was unable to answer and suggested that he investigate and report back to her. Thanks for the help. --Robert
 
Bad odor implies hydrogen sulfide, plus other sulfur compounds (if you're really interested, I can point you at some references on sulfur chemistry --- it ain't trivial). Boiling aqueous solutions of sulfides in air is a very mild oxidizing set of conditions that will oxidize sulfide to elemental sulfur (compared to boiling elemental sulfur in water under anaerobic conditions to get hydrogen sulfide). It's not adequate for treatment to produce potable water, nor can it be distilled too successfully, the hydrogen sulfide boils off and condenses with the water.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
