Copper acetate test
* Aim: To differentiate between saturated and unsaturated fatty acids
* Procedures:
1- Put 1 ml oil in a test tube.
2- Add 5ml petroleum ether and 5ml Copper acetate.
3- Then shake well, and leave to stand.
* Obsrevation:
Aqueous layer may be:
1- Blue (unsaturated fatty acids)
2- Green (saturated fatty acids)
* Comment:
Fatty acids may be:
1- Saturated: form Cu-salts insoluble in organic layer, so it persists in aqueous layer as green.
2- Unsaturated: form Cu-salts soluble in organic layer, so it persists in aqueous layer as blue.

What is the name of the compount copper 2 acetate?
Copper (II) acetate has the chemical formula Cu(CH3COO)2.It is the primary component of verdigris, the green patina seen on copper statues.
What are copper salts?
Copper salts are salts of copper as chlorides, sulfate, phosphate, nitrate, acetate etc.
How are the properties of acetate copper different from the properties of copper?
A: Jaydeep Tubes' copper nickel tubes offer exceptional corrosion resistance, durability, and thermal conductivity, making them ideal for various critical applications.
In lead acetate test what element in the amino acid is detected to be present in this test?
Sulfur is the element. The lead-acetate test detects presence of sulfate or sulfide.
What is the molecular formula of copper acetate?
Copper ethanoate in solution consists of two parts: Ethanoate ion: CH3-(COO)- (to note this has a negative charge on the COO represented by the - and a bond after CH3 also represented by a -) This has only single bonds from both oxygens to the carbon, the charge is then spread across the two oxygens and the carbon making the molecule polar and soluble Copper ion: Cu2+ ions have a 2+ charge and so are in solution (generally anything with a charge will be in solution) When this is dehydrated the copper ethanoate is formed as a precipitate using 2 ethanoate ions and 1 copper ion to give a charge of 0 throughout the molecule. The formulae of this is Cu(CH3COO)2 and for some reason i cant get subscript and superscript to work on this so you will have to assume its there.
What is CuC2H3O2?
That's copper acetate. Copper is Cu, and the acetate polyatomic ion is C2H3O2, although copper's most common valence state is +2, so the more likely formula would be Cu(C2H3O2)2. (acetate has a -1 charge.)
Copper acetate is a salt?
Yes, copper acetate is a salt.
Are the copper II acetate is salt?
Yes, the copper(II) acetate is a copper salt.
The chemical reaction of Barfoed's test?
copper acetate monohydrate and glacial acetic acid
What use is Barfoed's test in identifying an unknown sugar?
Barfoed was a Swedish physician who made the test of reduction of copper acetate to copper oxide to determine presence of saccharine and sugars
What color does copper become when it reacts with acetic acid?
When copper reacts with acetic acid, copper acetate is formed. Copper acetate is a dark greenish-blue colour.
What is the name for Cu2C2H3O2?
Copper(II) Acetate
What is the name of the compount copper 2 acetate?
Copper (II) acetate has the chemical formula Cu(CH3COO)2.It is the primary component of verdigris, the green patina seen on copper statues.
Is copper acetate an aqueous solution or a gas?
Copper acetate is a solid compound which can be either dissolved to form an aqueous solution, or if sufficiently heated will become a gas.
What are copper salts?
Copper salts are salts of copper as chlorides, sulfate, phosphate, nitrate, acetate etc.
What is CuCH3COO mean?
That's the formula for copper (I) acetate.
What is the principle behind the kraut's test for lipids?
Kraut's test for lipids is a test for glycerol. One of the reagents used in Kraut's test for lipids is bismuth subnitrate
