When excess of ammonia is added to aqueous zinc sulfate does the precipitate dissolve?
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.
Aqueous lead chloride reacts with aqueous sodium sulfate to produce a lead sulfate precipitate and aqueous sodium chloride?
yes
How can you Precipitate beta casein by using ammonium sulfate?
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.
When an aqueous solution of lithium chloride is mixed with an aqueous solution of ammonium sulfate what happens?
No reaction occurs
What is the balanced equations for Barium chloride ammonium sulfate yields barium sulfate ammonium chloride?
(NH4)2SO4(aq) + BaCl2(aq) → 2NH4Cl(aq) + BaSO4(s). Barium sulfate is the precipitate.
When excess of ammonia is added to aqueous zinc sulfate does the precipitate dissolve?
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.
Is ammonium sulfate aqueous?
No, by itself it is not. If dissolved in water it would then be aqueous.
Aqueous lead chloride reacts with aqueous sodium sulfate to produce a lead sulfate precipitate and aqueous sodium chloride?
yes

What is the balanced equations for Barium chloride ammonium sulfate yields barium sulfate ammonium chloride?
(NH4)2SO4(aq) + BaCl2(aq) → 2NH4Cl(aq) + BaSO4(s). Barium sulfate is the precipitate.
What can you conclude about a sulfate test on an unkown chemical and there precipitation observed?
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.)
What will happen if magnesium sulfate is combined with ammonium carbonate?
Magnesium carbonate - MgCO3 - a white precipitate is formed.
What is the balanced equation for the reaction between aqueous ammonium sulfate and aqueous barium acetate?
Ammonium and acetate don't react. Only ... ... are precipitating to solid. (SO42-)aq + (Ba2+)aq --> (BaSO4)s
A precipitate is expected to form when an aqueous solution of sodium sulfate is added to an aqueous solution of what is it ironIII chloride potassium chloride magnesium chloride or barium chlori?
The precipitate will be barium sulfate. The reaction is as follows:BaCl2(aq) + Na2SO4(aq) ==> 2NaCl(aq) + Ba(SO4)(s)
What do you get when you mix aqueous cuso4 copper sulfate and nahco3 sodium bicarbonate together?
You get a precipitate that is a sky blue and clear solution.
What is the Equation for aqueous solutions of barium chloride and sulfuric acid when mixed produce a precipitate of barium sulfate and aqueous hydrochloric acid?
BaCl2 + H2SO4 → BaSO4 + 2HCl Reactants Products
