What else can I help you with?
You used ammonia on your copper pots will it dissolve the copper?
Yes. Adding aqueous ammonia to copper with dissolve the copper in this reaction: Cu (s) + 2NH4OH (aq) > Cu(OH)2 (s) + 2NH4+ (aq)
Does extra addition of ammonia dissolve CopperII sulfide?
No, the addition of extra ammonia will not dissolve Copper II sulfide. Copper II sulfide is insoluble in water and ammonia solution; it does not react with ammonia to form soluble complexes.
What would you expect to observe if a sample of ammonia gas collected were bubbled into aqueous copper ii sulphate until no further change took place?
If a sample of ammonia gas were bubbled into aqueous copper (II) sulfate until no further change took place, you would observe a deep blue color forming due to the formation of a complex copper-ammonia compound. This complex, [Cu(NH3)4(H2O)2]2+, is responsible for the color change.
Is copper II Hydroxide a base?
Yes, copper II hydroxide is a base. It is an insoluble base that forms when copper ions react with hydroxide ions in an aqueous solution, leading to the precipitation of the copper II hydroxide compound.
Is copper iodide soluble?
Copper iodide is sparingly soluble in water, meaning it dissolves only to a small extent. It is more soluble in concentrated aqueous ammonia and potassium iodide solutions.

What is the colour change before and after Aqueous ammonia is added to a test tube containing a precipitate of copper II hydroxide and the precipitate dissolves?
The precipitate of copper II hydroxide is initially blue-green. When aqueous ammonia is added, the precipitate dissolves to form a deep blue solution due to the formation of a complex ion called tetraamminecopper (II) complex.

Why copper ammonia complex is more soluble in water than copper pyridine complex?
The copper ammonia complex is more soluble in water than the copper pyridine complex primarily due to the stronger interaction between ammonia and water molecules compared to pyridine. Ammonia can form hydrogen bonds with water, enhancing solubility, while pyridine, being a weaker hydrogen bond donor, does not interact with water as effectively. Additionally, the geometry and the charge distribution of the copper ammonia complex allow for better solvation in an aqueous environment, further increasing its solubility.
What happen when copper iii sulphate solution react with ammonia?
When copper(III) sulfate solution reacts with ammonia, a dark blue precipitate of copper(II) hydroxide is formed. This happens due to the displacement of the ammonia ligands by hydroxide ions in solution, resulting in the precipitation of copper(II) hydroxide. The reaction can be represented as CuSO4 + 2NH3 + 2H2O -> Cu(OH)2 + (NH4)2SO4.
Is CuCl aqueous?
CuCl (copper(I) chloride) can be dissolved in water to form an aqueous solution, but it has limited solubility. When CuCl is added to water, it does not fully dissociate, resulting in a partially saturated solution. Therefore, while CuCl can exist in an aqueous form, it does not completely dissolve like more soluble salts.
What happen when copper sulfate mixed with ammonia?
When copper sulfate is mixed with ammonia, a deep blue precipitate of copper hydroxide forms. This reaction occurs due to the ammonia forming a complex with the copper ions in the copper sulfate solution.
Are ammonia and copper mixed together a chemical?
1. Ammonia (gas, NH3) and copper (solid, Cu) cannot be mixed. 2. Ammonia can react with copper salts in water solutions.
What is the chemical equation for aqueous strontium sulfide and aqueous copper sulfate?
The chemical equation for the reaction between aqueous strontium sulfide (SrS) and aqueous copper sulfate (CuSO4) is: SrS + CuSO4 → SrSO4 + CuS Strontium sulfate (SrSO4) and copper sulfide (CuS) are the products of this double displacement reaction.
