Water molecules bind to ammonium and sulfate ions rather than proteins.
Yes. The ammonia will form ammonium hydroxide. The ammonium cation (NH4+) will react with SO4^2- to form the soluble salt ammonium sulfate, (NH4)2SO4. According to Le Chatelier's Principle, this will push the reaction to the right, thus forming more ammonium sulfate from the insoluble zinc sulfate.
The balanced chemical equation for the reaction between aqueous ammonium sulfate (NH4)2SO4 and aqueous barium acetate Ba(C2H3O2)2 is: (NH4)2SO4 + Ba(C2H3O2)2 → BaSO4 + 2NH4C2H3O2. In this reaction, a white precipitate of barium sulfate (BaSO4) is formed.
Addition of ammonium sulfate uses up the available polar contacts with water, effectively stealing them from the proteins and causing them to aggregate, so if you add ammonium sulfate to milk as it is slightly heated (40C), after enough addition all of the protein will precipitate out, that is after the ammonium sulfate takes up all of the available polar bond from the water. After that you would still have to isolate and purify the casein. I suggest using acidification or column chromatography.
The reaction is a double displacement reaction as lead chloride and sodium sulfate exchange ions to form lead sulfate and sodium chloride. The lead sulfate is insoluble in water, forming a precipitate, while the sodium chloride remains in solution as ions. This reaction is used to separate lead ions from a mixture.
There is a difference in salting out process and providing stability to the proteins.. so Hofmeister practically found the series called Lyotropic series and also by his name. according to it : anions... citrate>sulphate>phosphate.... cations... ammoium>potasium>......

When ammonium sulfate is added to a protein solution, it disrupts the protein's structure by reducing the solubility of the protein. This causes the proteins to aggregate and precipitate out of the solution.

Ammonium sulfate is commonly used in protein precipitation because it can selectively precipitate proteins based on their size and charge. By adjusting the concentration of ammonium sulfate, different proteins can be selectively precipitated, allowing for the purification and concentration of specific proteins from complex mixtures. Additionally, ammonium sulfate is relatively inexpensive, soluble in water, and widely available for laboratory use.

Differential ammonium sulfate precipitation is a technique used to purify proteins based on their solubility in ammonium sulfate at different concentrations. By gradually increasing the salt concentration, proteins with higher affinity for ammonium sulfate will precipitate at lower concentrations, allowing for selective recovery and purification of target proteins from a mixture. This method helps separate proteins by exploiting differences in their solubility characteristics.
No, by itself it is not. If dissolved in water it would then be aqueous.

A precipitate is expected to form when an aqueous solution of sodium sulfate is added to an aqueous solution of barium chloride. This reaction results in the formation of insoluble barium sulfate, which appears as a white precipitate.
When you mix aqueous CuSO4 (copper sulfate) and NaHCO3 (sodium bicarbonate) together, a double displacement reaction occurs. The products are a precipitate of CuCO3 (copper carbonate) and aqueous Na2SO4 (sodium sulfate).
If you treat an unknown sample with ammonium sulfate (or any other soluble sulfate) and get a precipitate, you can conclude that there's a metal ion which forms insoluble sulfates in it. (Pretty much all ammonium salts are soluble, so you don't need to worry about the anion.)
Yes, aqueous ammonia (NH3) and iron(II) sulfate (FeSO4) can react to form a green precipitate of iron(II) hydroxide (Fe(OH)2) and ammonium sulfate (NH4)2SO4. The balanced chemical equation for this reaction is: 2NH3 + FeSO4 -> Fe(OH)2 + (NH4)2SO4.
