What is ammonia used to test for copper in a solution?
Ammonia is used to test for the presence of copper in a solution because it forms a deep blue complex with copper ions. This complex is known as Schweizer's reagent and can be used as a qualitative test for the presence of copper ions.
What metallic element is used to make electrical wire and pots?
Copper is commonly used to make electrical wires due to its excellent conductivity. Aluminium is often used for making pots and pans because of its lightweight properties and resistance to corrosion.
How was copper first used?
When copper was fiirst discovered it was used to make pots and pans for cooking. Now copper is no longer used to make pans/pots as there are more efficient materials and copper is now mainly used to make wires.
What is the chemical formula for the deep blue complex formed when copper hydroxide reacts with ammonia?
Copper(II) hydroxide reacts with a solution of ammonia to form a deep blue solution consisting of the [Cu(NH3)4]2+ complex ion. Copper(II) hydroxide in ammonia solution, known as Schweizer's reagent, possesses the interesting ability to dissolve cellulose. This property led to it being used in the production of rayon, a cellulose fiber. Since copper(II) hydroxide is mildly amphoteric, it dissolves slightly in concentrated alkali, forming [Cu(OH)4]2-.
What happens when you mix ammonia with water?
When you mix ammonia with water, ammonia can dissolve in water to form ammonium hydroxide, which increases the pH of the solution. This creates a basic solution that can be used for cleaning purposes. Alternatively, ammonia gas will also dissolve in water forming a weak base.
Can copper pots be used outside?
Copper pots should be lined before they are used for plants. Copper can be absorbed by the roots of the plant and can kill the plant. Copper pots used outside may develop a green patina from oxidation.
Where does copper pots come from?
Copper has been used for thousands of years. Ancient civilizations used copper. The old kingdom of Egypt had copper tools, jewelry, and pots. This was 7,000 to 5,000 years ago.

The role of ammonia in Tollen?
Ammonia is used as a ligand in order to dissolve the insoluble Silver ions under alkaline conditions.
What are different types of metal used to make pots?
The most popular metals used for making pots are aluminum, cast iron, stainless steel, and copper.
What metallic element is used to make electrical wire and pots?
Copper is commonly used to make electrical wires due to its excellent conductivity. Aluminium is often used for making pots and pans because of its lightweight properties and resistance to corrosion.
Common Material used in Harappan civilization?
copper ,brass ,clay pots etc.
What acid will eat copper but not gold?
Nitric acid can dissolve copper but not gold. Gold is resistant to most acids, including nitric acid, which is commonly used to dissolve copper.

What household ammonia used for?
Cleaning windows. Some greasy deposits, those around stoves particularly, will dissolve in it.
