Water Archives

I was analyzing a salt in chem lab, and out of 2 guesses my professor told me that potassium was the cation. The anion has to be CO3, SO4, PO4, Cl, or I. Which of these is NOT soluble in water?

Hello! I have chopped up strawberries that I am dehydrating. I spread them out on a paper towel and remove the excess water.

Can you show the work so I can understand

Glycol Dehydration Unit Operation

Chlorobutane = C4H9Cl
Sodium thiosulfate = Na2S2O3
Potassium sulfate= K2SO4

I need three different explanations. One explaning why chlorobutane doesn’t dissolve in water and two explaning why sodium thiosulfate and potassium sulfate do.

Thanks!

How much potassium nitrate has to dissolve in water to absorb 100kJ of heat? (answer in kg)
Potassium nitrate has a lattice energy of -163.8kcal/mol and a heat of hydration of -155.5kcal/mol.

I have tried this many times with many different explanations but i cannot get the right answer so a solution and explanation would be great! Thanks!

This Boa constrictor was presented to me with a severe case of stomatitis ulcerosa. The roof of the mouth was severely swollen and in the tissue there were holes filled with puss and dead flesh. Applying pressure on the nose resulted in puss running out of holes in the snake’s mouth. (holes which shouldn’t have been there to begin with… ) The vomero-nasal organ (Jacobsons organ) was completely destroyed and some of the bones in the upper jaw were also affected by the stomatitis. The fluids running over the right eye could not be drained due to the swelling of the surrounding tissue, hence the swelling of the head.. This animal was also severely dehydrated and malnourished, there is a video in my upload-list with the intestinal parasites this animal also had to deal with (flagellates and pinworms) ( www.youtube.com ) Unfornunately, despite treatment with antimicrobials, daily cleaning the oral mucosae subcutaneous fluids and agressive antiparasitic treatment (and a Sh*tload of money spent) this animal died after 6 or 7 days of intensive care.. Had the animal been brought in sooner (say, a month or so…) I am convinced that it would have been alive still. Some people should not be allowed to keep animals as pets.
