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.

Is (NH4)2SO4 a solid?
Hi, This is what i got, with a little research and asnwer checking, I'm 16. :) Ammonium Bisulfite, Is a white crystal structured solid, formed when partially neutralised Sulfuric Acid becomes an aerosol (suspension of fine solid particles or liquid droplets in a gas) by using gaseous Ammonia (NH4), It has the chemical formula [(NH4)HSO4] is also known as Ammonium Hydrogen Sulfate. Industrial: Collected as an extra product of flue gas desulfurization. It can also be further reacted with ammonia (in the gas state) to form Ammonium Sulfate [(NH4)2SO4], which is a great fertilizer. This was not my source, but my answer checking website URL: http://en.wikipedia.org/wiki/Ammonium_bisulfate Hope this helps. Jake P. :)
What risks are there when using ammonium nitrate?
It depends completely on what you are using it for. It is slightly toxic, and it is also a strong oxidizer (I think it's even stronger than ammonium perchlorate). Mixing it with metal powders or combustible materials can cause an explosion.
How do you capture CO2 using ammonium hydroxide?
Co2 +2 nh4oh = (nh4)2co3 + h2o
What is aqueous silver nitrate and potassium bromide combine to form a precipitate?
When a substance is aqueous, it means that it is dissolved in water. In aqueous reactions, the reaction is always a double replacement reaction, meaning one ion of a compound will switch with an ion from the other compound. A precipitate is an substance that is not soluble in water, meaning it cannot be dissolved. You can tell whether or not a substance is precipitate using a solubility chart. Therefore, using a solubility chart, we can tell that the product silver bromide will be the precipitate and the product potassium nitrate will be aqueous.
Chemical formula of ammonium thiosulphate?
The formula for the ammonium cation is NH4+. The formula for the thiosulfate anion is S2O32-. To balance the charges out to zero, twice as many ammoniums are needed than thiosulfates. This is shown using a subscript in the formula: (NH4)2S2O3
Explain why gravimetric analysis is suitable for the analysis of sulfate ions but not ammonium ions?
The sulphate ions as anion get precipitate easily using suitable precipitants unlike ammonia ions.
What need to be taken in mind when using Ammonium sulfate for fertilizer application?
Ammonium sulfate is a kind of excellent nitrogen (commonly known as ammonium sulphate), which is suitable for general soil and crop. Using ammonium sulfate can make the branches and leaves grow well so as to improve the quantity and quality of the fruit yield and enhance disaster resistance ability. Therefore, ammonium sulfate is widely used as a basic fertilizer, additional fertilizer and seed manure.Some tips when using ammonium sulfate:1. Due to its weak acid, it can't contact with other basic fertilizer or alkaline substances or mixed fertilizer;2. No long-term use of ammonium sulfate on the ground. Otherwise, soil acidification and hardening would occur ;3. No use in acid soil.
What is a chemical reaction that produces ammonia using ammonium sulfate and one other reactant?
Alcohol
What is the chemical equation for the preparation of ammonium bromide using potassium bromide and ammonium sulfate?
2 KBr + (NH4)2SO4 -> 2 NH4Br + K2SO4
What is the theoretical reasons in using Ammonium thiosulfate Dipropylene Glycol and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes?
The theoretical reason for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is their ability to be used as wetting agents.
What is the theoretical reasons in using use Ammonium thiosulfate Dipropylene Glycol and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes?
The theoretical reasons for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is because they are wetting agents.
How does coagulation of casein proteins take place using Rennet or Acid?
Casein has a negative charge and it is dispersed in milk, to make cheese one must denature casein to coagulate it. Using the enzyme rennin, found in rennet, the casein will coagulate.
How do you balance Fe O2 Fe3O4?
By this following reaction:Fe2+ + Fe3+ + OH- ----> Fe3O4 + H2OIt comes out as a black precipitate. Generally this reaction is done by using Iron(II) Chloride, Iron(III) chloride and Ammonium hydroxide.
How has industry overcome the release of harmful sulfur dioxide through smelting?
The sulfur dioxide can be captured in a solution to form ammonium sulfate, a fertilizer. A method using electrons bombardment is known for this process.
How casein extract from milk?
in lab using acetic acid
What is meant by Liquid Rennet?
Rennet is an enzyme that is made by baby calves to digest milk. It acts by cleaving off the tails of Kappa Casein that surround the casein micelle, which allows the casein micelles to get closer to each other, thus causing them to bond together and precipitate. Rennet can be made by either harvesting out of the stomachs of the boy calves, that the farmer does not want and so sends to the freezing works. It can also be made synthetically using microbes. Hence you can have calf rennet or microbial rennet. Calf rennet is generally more effective, but it costs more and there is a limited supply. Rennet is used in the dairy industry to make both cheese and rennet casein.
Can you prepare ammonia using calcium oxide and ammonium chloride?
Yes. Ammonium salts such as ammonium chloride will react with a strong base to yield ammonia.
