In experiment preparation of copper (II) oxalate complex why the melting point of copper (II) oxalate not meet theory?
Wiki User
∙ 6y ago
The observed melting point of copper (II) oxalate may not meet the theoretical value due to impurities in the sample or incomplete reaction during preparation. Factors such as water content, incomplete conversion of starting materials, or presence of unreacted starting materials can influence the melting point. It is essential to ensure purity of reagents, control reaction conditions, and thoroughly dry the product to accurately determine the melting point.

Choose the correct formula for this compound silver oxalate?
The correct formula for silver oxalate is Ag2C2O4.
Why you add H2o2 in preparation of ferric oxalate?
Hydrogen peroxide (H2O2) is added during the preparation of ferric oxalate to help oxidize iron(II) to iron(III). This oxidation step is necessary to convert iron(II) oxalate to ferric oxalate, which is a key intermediate in the synthesis of other iron compounds for various applications, such as pigments or catalysts.
Why potassium oxalate is acidified before titration?
If the temperature is too low (below 55 degrees celsius), the interaction between the oxalate and the potassium permanganate will move too slow as to be used as a practical lab experiment. *** Above 60 degrees celsius, oxalate acid begins to decompose, so it's important to stay in this range.
How does oxalate bind to copper in copper II oxalate?
Oxalate binds to copper in copper II oxalate through coordination bonds, where the oxygen atoms in the oxalate ion donate electron pairs to form bonds with the copper ion. This results in the formation of a stable complex where the copper ion is surrounded by the oxalate ligands.
What is the chemical formula for chromium oxalate?
The chemical formula for chromium oxalate is Cr2(C2O4)3.
Choose the correct formula for this compound silver oxalate?
The correct formula for silver oxalate is Ag2C2O4.

What is the green precipitate in preparation of chromium oxalate complexes?
The green precipitate in the preparation of chromium oxalate complexes is likely chromium(III) oxalate. This compound forms when a soluble chromium salt reacts with oxalic acid or oxalate ions in solution. The green color is characteristic of chromium(III) compounds.

What is the product between Sodium Hydroxide and Potassium trioxalate Chromium 3 trihydrate?
A complex,potassium tri oxalate,.........
What is the chemical formula for chromium oxalate?
The chemical formula for chromium oxalate is Cr2(C2O4)3.
What is the Product of aluminium hydroxide oxalic acid and potassium oxalate?
The product of aluminium hydroxide and oxalic acid is aluminium oxalate, while the product of aluminium oxalate and potassium oxalate is potassium oxalate and aluminium oxalate.
What is the structure of urea oxalate?
Urea oxalate is a complex organic compound formed by the reaction between urea and oxalic acid. It has a crystal structure with urea and oxalic acid molecules arranged in a specific pattern within the crystal lattice. The molecular formula of urea oxalate is (CO(NH2)2)2·C2H2O4.
What can be the viva questions on oxalate ions?
Oxalates are salts of oxalic acid containing oxalate ion. Oxalate ion is a dianion. Upon protonation, oxalate ion forms a commonly known compound, oxalic acid. The commonly known oxalate salts are sodium oxalate, potassium oxalate etc. The calcium metal ion reacts with oxalate ion to form an insoluble precipitate of calcium oxalate, which is the primary constituent of most of the common kind of Kidney stones.
Excessive quantities of wash water are added to the calcium oxalate and water precipitate how does this affect the mass?
Adding excessive quantities of wash water to the calcium oxalate and water precipitate might result in the loss of some of the precipitate during filtration due to increased solubility. This could lead to an underestimate of the mass of calcium oxalate obtained in the experiment.
What is the chemical abbreviation for Ferric Ammonium Oxalate?
The chemical abbreviation for Ferric Ammonium Oxalate is FeNH4C2O4.
