Why is AgNO3 used as the precipitating agent in determining the chloride?
It forms a precipitate with chloride:Ag+aq + Cl-aq --> AgCl precip.solidBecause silver chloride (AgCl) is formed as a result of the reaction; silver chloride is very insoluble, an important quality for gravimetric analysis.
What causes a precipitate to form when barium hydroxide solution and sulphuric acid are mixed?
When barium hydroxide solution is mixed with sulfuric acid, a white precipitate of barium sulfate is formed due to a double displacement reaction. Barium sulfate is insoluble in water and thus forms a solid precipitate. This reaction is used in chemistry labs to test for the presence of sulfate ions.
What happens when an aqueous solution of sodium sulphate reacts with an aqua solution of barium chloride?
The immediate response is a milky appearance. After 5-10 minutes a precipitate of BaSO4 will settle out of solution. You will obtain a cloudy, white precipitate that will remain so infantily. This is a precipitation reaction (the formation of an insoluble salt from a solution of soluble ones) which occurs because barium sulfate is insoluble, so when mixed, the barium ions react with the sulfate ions to form a white precipitate of barium sulfate The net ionic equation is: Ba2+(aq) + SO42-(aq) ----> BaSO4(s)
How is calcium sulfate used in food production?
Calcium sulfate is used in food production as a food additive and firming agent. It is commonly used to improve the texture and stability of foods such as tofu, cheese, and baked goods. Additionally, calcium sulfate can be used as a coagulant in the production of certain types of cheese.
What is left after evaporating copper sulfate?
After evaporating copper sulfate, you are left with solid copper sulfate crystals. These crystals can be collected and then used for further experiments or applications, such as in the preparation of other copper compounds or as a drying agent.

Why is Barium Sulphate used in the limit test for sulphates?
Barium sulfate is used in the limit test for sulphates because it forms a highly insoluble precipitate with sulfate ions. This property allows for the qualitative or quantitative determination of sulfate ions in a sample by measuring the amount of barium sulfate precipitate formed. The formation of a white precipitate confirms the presence of sulfate ions in the sample.
Insoluble base used to make copper sulfate?
Sodium hydroxide (NaOH) is an insoluble base that can be used to make copper sulfate. When sodium hydroxide is added to a solution of copper sulfate, a blue precipitate of copper hydroxide forms. This precipitate can be filtered and then reacted with sulfuric acid to produce copper sulfate.
Function of isopropanol and ethanol in plasmid isolation?
Cold ethanol or isopropanol is used to precipitate the plasmid DNA, DNA is insoluble in alcohol and clumps or clings together. Centrifuging will cause the precipitate to form a pellet which can be decanted from the unwanted supernatant. Where as if compared with RNA isolation isopropanol is less efficient in precipitating RNA, where in presence of Lithium chloride or ammonium ions can give a good yield
Is sodium sulfide plus copper sulfate equals copper sulfide percipitate?
Yes, when sodium sulfide is mixed with copper sulfate, a reaction occurs that forms a precipitate of copper sulfide. This is a common chemical reaction used to demonstrate the formation of a precipitate in chemistry experiments.
What causes a precipitate to form when barium hydroxide solution and sulphuric acid are mixed?
When barium hydroxide solution is mixed with sulfuric acid, a white precipitate of barium sulfate is formed due to a double displacement reaction. Barium sulfate is insoluble in water and thus forms a solid precipitate. This reaction is used in chemistry labs to test for the presence of sulfate ions.
Aqueous lead chloride reacts with aqueous sodium sulfate to produce a lead sulfate precipitate and aqueous sodium chloride?
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.
What reagents are used to confirm Ba plus 2?
To confirm the presence of Ba2+ ions, you can use a sulfate ion-containing solution, such as sulfuric acid (H2SO4), to form a white precipitate of barium sulfate (BaSO4). This precipitate is insoluble in water and confirms the presence of Ba2+ ions in the solution.
What happens when an aqueous solution of sodium sulphate reacts with an aqua solution of barium chloride?
The immediate response is a milky appearance. After 5-10 minutes a precipitate of BaSO4 will settle out of solution. You will obtain a cloudy, white precipitate that will remain so infantily.

How does aqueous ammonium sulfate precipitate proteins?
Aqueous ammonium sulfate precipitates proteins by reducing the solubility of proteins in water. As the concentration of ammonium sulfate increases in the solution, it competes with the protein for water molecules, causing the protein to become less soluble and eventually precipitate out of the solution. This method is commonly used in protein purification techniques like salting out.
What is the role of anhydrous sulfate?
Anhydrous sodium sulfate is considered as a drying agent. It is used in expirements to remove water from a solution or during an expirement. hope this helps.
Can precipitation be used as a separation technique?
Yes, precipitation can be used as a separation technique. It involves converting a dissolved substance into a solid by adding a precipitating agent, allowing the solid to settle out of the solution, and then separating the solid from the liquid by filtration or decantation. This process is commonly used in chemistry and wastewater treatment to remove impurities from a solution.
