Name a salt which gives white precipitate on ammonium hydroxide solution and is insoluble in excess?

One such salt would be aluminum chloride since it is soluble but when reacted with ammonium hydroxide, the insoluble aluminum hydroxide forms a precipitate. Not sure what is meant by "is insoluble in excess", however.

What happens when aluminum sulfate reacts with strontium hydroxide?
When aluminum sulfate reacts with strontium hydroxide, aluminum hydroxide and strontium sulfate are formed as products in a double displacement reaction. Aluminum hydroxide is insoluble in water and will precipitate out of the solution, while strontium sulfate will also be a precipitate since it is insoluble in water.
Why does a solid fall out of its solution?
When a solid falls out of solution, it is called a precipitate. A precipitate is formed when a chemical reaction occurs in a solution and the product that is made is insoluble.
What is the density of ammonium hydroxide?
The ammonium hydroxide solution 28 % has a density of 0,9 g/cm3 at 25 oC.
How insoluble salt can be recover?
Insoluble salts can be recovered through precipitation reactions by mixing two soluble salts that will react to form the insoluble salt as a precipitate. The precipitate can then be filtered out from the solution. Alternatively, the insoluble salt can be recovered by evaporating the solvent to concentrate the solution and allow the salt to crystallize out.
Name of NH4OH?
in catalyst (AL2O3)with heat(450C) = CH3NH2 + (CH3)2NH + (CH3)3N
Will Ammonium hydroxide and Hydrochloric acid form a precipitate?
No, ammonium hydroxide and hydrochloric acid will not form a precipitate when mixed together. The reaction between them will result in the formation of ammonium chloride, which will remain dissolved in the solution.
Why there is turbidity when coppper sulfate solution is treated with ammonium hydroxide?
The turbidity is due to the formation of the insoluble copper hydroxide.
Why does copper II nitrate and sodium hydroxide make a precipitate?
When copper (II) nitrate and sodium hydroxide are mixed, a chemical reaction occurs, resulting in the formation of copper (II) hydroxide, which is insoluble in water. This insoluble compound precipitates out of the solution, appearing as a solid.
Will a precipitate form if solutions of the soluble salts AgNO3 and NaOH are mixed?
Yes, a white precipitate of silver hydroxide (AgOH) will form when solutions of silver nitrate (AgNO3) and sodium hydroxide (NaOH) are mixed. Silver hydroxide is insoluble in water, so it will precipitate out of the solution.
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
Is Ammonium Nitrate solution and aqueous potassium phoshphate a precipitate?
When ammonium nitrate solution is mixed with aqueous potassium phosphate, a precipitate of ammonium phosphate forms due to a double displacement reaction. Ammonium phosphate is insoluble in water and therefore will appear as a solid precipitate in the solution.
Why do the solution of the white precipitate of Zinc hydroxide dissolve in excess of Ammonium hydroxide?
The white precipitate of zinc hydroxide dissolves in excess ammonium hydroxide because of the formation of the complex ion [Zn(NH3)4]2+. This complex ion is soluble in water, leading to the dissolution of the precipitate. The excess ammonium hydroxide provides additional ammonia molecules to form more of the soluble complex ions, increasing the solubility of zinc hydroxide.
What happens when aluminum sulfate reacts with strontium hydroxide?
When aluminum sulfate reacts with strontium hydroxide, aluminum hydroxide and strontium sulfate are formed as products in a double displacement reaction. Aluminum hydroxide is insoluble in water and will precipitate out of the solution, while strontium sulfate will also be a precipitate since it is insoluble in water.
Why does a precipitate form when ammonium hydroxide and sodium chloride mix with dry ice?
When ammonium hydroxide and sodium chloride mix, they react to form ammonium chloride, which is a white solid precipitate. The dry ice (solid carbon dioxide) added to the solution lowers the temperature, which promotes the formation of the solid precipitate.
What is a solid in a solution?
A precipitate is a solid in a solution. The precipitate will not dissolve in the solution, it is insoluble!! The opposite of a precipitate is a solute.
Is ammonium hydroxide a dilute solution?
Yes, ammonium hydroxide is a dilute solution of ammonia gas dissolved in water.
What is the precipitate formed when AlSO43 plus NH4OH?
When aluminum sulfate (Al2(SO4)3) reacts with ammonium hydroxide (NH4OH), the precipitate formed is aluminum hydroxide (Al(OH)3). Aluminum hydroxide is a white, gelatinous solid that forms when the aluminum ion in the sulfate reacts with the hydroxide ion in ammonium hydroxide.
