Why a pale blue precipitate of copper hydroxide is formed when ammonia is passed through copper sulphate?
When ammonia is added to a solution of copper sulfate, it forms a complex with the copper ions to produce a pale blue precipitate of copper hydroxide. The complex forms because ammonia acts as a ligand, coordinating with the copper ions to create a stable compound. This reaction is a result of the displacement of the sulfate ions by ammonia in the copper sulfate solution.

What derivatives of ammonia?
The derivatives of ammonia include ammonium ions (NH4+), ammonia salts, and ammonium compounds like ammonium hydroxide (NH4OH). Ammonia can also be further transformed into various organic and inorganic compounds through reactions with other substances.
When carbon iv oxide is bubbled through calcium hydroxide what is the white precipitate formed?
The precipitate formed is Calcium Carbonate (CaCO3).
How do you dissolve ammonia gas in water?
To dissolve ammonia gas in water, simply bubble the gas through the water. Ammonia gas will react with water to form ammonium hydroxide. This process will continue until the water is saturated with ammonia gas, after which it will not dissolve any more.
Why do soap manufacturers use sodium hydroxide not ammonia?
Sodium hydroxide is commonly used in soap making because it creates a chemical reaction with the fats and oils to form soap through a process called saponification. Ammonia is not typically used in soap making because it does not have the same properties to facilitate this reaction.
How can aluminum sulphate dissolve copper?
the aluminium is split with the sulphate ion. this leaves the sulphate on its own with a charge. the copper then takes the place of the aluminium turning the charge of the sulphate ion to neutral, this leaves the aluminium and copper sulphate.
What are the two ways to prepare ammonium sulphate?
The two common ways to prepare ammonium sulphate are neutralizing ammonia gas with sulfuric acid or reacting ammonium hydroxide with sulfuric acid. In the first method, ammonia gas is bubbled through sulfuric acid to form ammonium sulphate. In the second method, ammonium hydroxide is slowly added to sulfuric acid to produce ammonium sulphate.
What derivatives of ammonia?
The derivatives of ammonia include ammonium ions (NH4+), ammonia salts, and ammonium compounds like ammonium hydroxide (NH4OH). Ammonia can also be further transformed into various organic and inorganic compounds through reactions with other substances.
What happens when ammonia is passed through aluminium sulphate solution?
When ammonia is passed through an aluminum sulfate solution, it reacts to form aluminum hydroxide, which precipitates out of the solution. This reaction occurs because ammonia acts as a base, raising the pH and causing aluminum ions to hydrolyze and form insoluble aluminum hydroxide. The overall process can be represented by the reaction: ( \text{Al}_2(\text{SO}_4)_3 + 6 \text{NH}_3 + 6 \text{H}_2\text{O} \rightarrow 2 \text{Al(OH)}_3 \downarrow + 3 \text{(NH}_4\text{)}_2\text{SO}_4 ). The aluminum hydroxide precipitate can then be filtered out from the solution.
When carbon iv oxide is bubbled through calcium hydroxide what is the white precipitate formed?
The precipitate formed is Calcium Carbonate (CaCO3).
How do you test presence of carbon dioxide?
Bubble the gas through limewater (calcium hydroxide), and then a white precipitate is formed, which is actually calcium carbonate.
How do you dissolve ammonia gas in water?
To dissolve ammonia gas in water, simply bubble the gas through the water. Ammonia gas will react with water to form ammonium hydroxide. This process will continue until the water is saturated with ammonia gas, after which it will not dissolve any more.
What salts and sodium hydroxide produce ammonia gas?
Ammonium chloride (NH4Cl) and ammonium sulfate ((NH4)2SO4) can produce ammonia gas when reacted with sodium hydroxide (NaOH) through a chemical reaction, known as the Hofmann elimination reaction. This reaction forms ammonia gas (NH3) and water (H2O) in the process.
Is it possible for sodium hydroxide to smell like ammonia in the cooling system of a car with a blown head gasket through the exhaust pipe?
Yes
What happens when CO2 is passed through a lime water for a long time?
When carbon dioxide (CO2) is passed through lime water (a saturated solution of calcium hydroxide, Ca(OH)2) for an extended period, it reacts with the calcium hydroxide to form calcium carbonate (CaCO3), which is a white precipitate. Initially, the lime water turns milky due to the formation of this precipitate. Over time, if excess CO2 is introduced, the precipitate can dissolve back into the solution, forming calcium bicarbonate, which is soluble in water.
What metal reacts with water to give a solution which forms a white precipitate with carbon dioxide?
Calcium. It reacts with water to form a solution of calcium hydroxide which can then react with carbon dioxide to form calcium carbonate, a white precipitate. You will get similar results with strontium and barium.
