What else can I help you with?
What do you expect to observe when a solution of potassium nitrate saturated at 343 k is cooled at room temperature?
When a saturated solution of potassium nitrate is cooled from 343 K to room temperature, you can expect to observe the precipitation of potassium nitrate crystals. As the temperature decreases, the solubility of potassium nitrate decreases, leading to an excess of solute that cannot remain dissolved. This will result in the formation of solid crystals settling out of the solution. Additionally, the concentration of the remaining solution will remain at saturation until all excess solute has precipitated.
Adding more solute to a saturated aqueous solution causes?
Adding more solute to a saturated aqueous solution causes the excess solute to precipitate out of the solution as solid particles. This process is known as precipitation and helps to decrease the concentration of the solute in the solution, allowing for more solute to dissolve.
What is the chemical solution for hydronium?
Hydronium ion is H+ ion or H3O+ ions aqueous solution that contains excess of H+ ions is known as hydronium solution or better, as acidic solution.
Does the large intestine store excess material?
It does not store excess material the rectum does that.
What is excess carbon in the blood?
and i no how ?
What is observe when aqueous ammonia is added in excess to a silver chloride solution?
When aqueous ammonia is added in excess to a solution of silver chloride, the white precipitate of silver chloride dissolves to form a colorless, tetrahedral complex ion called [Ag(NH3)2]+. This complex ion is soluble in excess ammonia due to the formation of a stable coordination complex.
Why should excess bromine water be avoided in the test for free tryptophan?
Excess bromine water should be avoided in the test for free tryptophan because it can cause the breakdown of tryptophan, leading to false negative results. Bromine water is a strong oxidizing agent that can react with tryptophan and other organic compounds, potentially altering the test outcome.
How do you dispose the excess bromine and other reagent containing bromine at the end of your experiment?
The excess bromine can be neutralized with a reducing agent like sodium thiosulfate. Once neutralized, it can be disposed of following proper waste disposal guidelines for hazardous chemicals. Other reagents containing bromine should be treated similarly, neutralizing if necessary before following waste disposal protocols.
What is a bromine neutralizer?
A bromine neutralizer is a chemical agent used to deactivate or stabilize residual bromine in water. This helps to prevent any excess or harmful bromine levels in water treatment processes, such as in pools or spas.
What forms from the reaction of bromine with acetophenone?
The reaction of bromine with acetophenone can yield several products, depending on reaction conditions. One common product is α-brominated acetophenone, where bromine adds to the alpha carbon of the carbonyl group. This reaction can also lead to dibrominated acetophenone if excess bromine is used.
How do you lower high bromine levels in a pool?
To lower high bromine levels in a pool, you can dilute the water by adding fresh water. Running the pool pump and filter system for an extended period can also help remove excess bromine. Additionally, using a bromine neutralizer or shock treatment specifically designed for lowering bromine levels can be effective.
How do you reduce bromine level in a pool?
To reduce bromine levels in a pool, you can dilute the water by adding fresh water. Alternatively, you can neutralize the excess bromine by adding sodium thiosulfate or a non-chlorine shock treatment. It's important to retest the water after making adjustments to ensure the bromine levels are within the recommended range.
Why does the precipitation of copper ion dissolve in excess aqueous ammonia?
Excess aqueous ammonia forms a complex with copper ions called tetraamminecopper(II) complex, [Cu(NH3)4]2+, which is soluble in water. This complex formation reduces the concentration of free copper ions in solution, causing the precipitation of copper ions to dissolve.
What means aqueous?
Aqueous means large excess of water. when we write the worf aq with a substance in a chemical reaction it means that the substance formed is dissolved in water. For eg- CaO(s) + H2O(l) -------> Ca(OH)2 (aq)
What is the name for a solution that has an excess of H plus ions and therefore breaks into H plus and another compound when placed in an aqueous solution?
acid or acidic
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.
What is the reaction of phenol with Bromine?
The hydroxyl group in phenol is an activating ortho/para director, but has some slight steric hindrance too ortho position substitution. Therefore, the predominant product of reaction between phenol and bromine will be 4-bromophenol, if reaction conditions are carefully controlled. With excess bromine, di- and tri-bromo phenols will be formed.
