Precipitate of salicylic acid dissolves after addition of excess sulphuric acid?
The precipitate of salicylic acid dissolves in excess sulphuric acid due to the formation of a complex between salicylic acid and sulphuric acid, which increases the solubility of the precipitate. This reaction results in the formation of a colorless solution, as the salicylic acid is converted into its conjugate base form.
What is the color of the salicylic acid-Fe3 complex?
The color of the salicylic acid-Fe3 complex is typically red or reddish-brown. This color is due to the formation of a complex between salicylic acid and iron ions, specifically Fe3+ ions, which gives the solution its characteristic color.
What is the rationale for the color reaction between salicylic acid and ferric chloride?
The color reaction between salicylic acid and ferric chloride is based on the formation of a complex between salicylic acid and ferric ion. The complex absorbs light in the visible range, resulting in a color change from pale yellow to purple or blue depending on the concentration of salicylic acid. This reaction is commonly used in analytical chemistry for qualitative detection of phenols.
What is the formation constant for dithiosulfato argentate?
The formation constant for dithiosulfato argentate, [Ag(S2O3)2]3-, is approximately 1.04 x 10^21. This complex is formed between silver ions and dithiosulfate ligands, resulting in a stable coordination compound.
What about the complex formation ability of lanthanides as campared to actinides?
describe the complex formation by lanthanides?
What is primarily responsible for the formation of the cells lysosomes?
Golgi complex
What is the formation of a complex molecule by removal of water?
The formation of a complex molecule by removing water is called dehydration synthesis. In this process, a molecule of water is removed as two smaller molecules join together to form a larger, more complex molecule.
A complex process required for the actual formation of ATP molecules?
chemiosmosis
A complex process required for the actual formation of ATP molecules is?
Chemiosmosis
What organelles is primarily responsible for the formation of the cells lysosomes?
Golgi complex
What is a computer language constant?
A constant is a primitive or complex object that does not vary. That is, once instantiated, its immutable members cannot be changed.
Salicyclic acid gives a positive test with FeCl3?
This is a commonly used test to detect the presence of phenolic hydroxyl groups in organic compounds. The reaction between salicylic acid and FeCl3 forms a complex with a purple color, indicating the presence of phenolic groups in the compound.
