In experiment preparation of copper (II) oxalate complex why the melting point of copper (II) oxalate not meet theory?
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 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?
Copper oxalate is supposed to be a ribbon-like molecule where each copper 2+ ions are surrounded by four oxygen atoms in a square plan. These four oxygen atoms involve two oxalate anions. A copper II oxalate molecule can be described as an infinite ribbon of alternatively copper (Cu 2+) and oxalate (C2O4 2-) groups. Each copper 2+ cation is linked by two oxalate groups by weak electrostatic interactions with the four oxygen atoms.
How does the oxalate ion function as a bidentate ligand in coordination chemistry?
The oxalate ion acts as a bidentate ligand in coordination chemistry by forming two bonds with a central metal ion. This allows the oxalate ion to coordinate with the metal ion from two different directions, creating a stable complex.

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 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.
