It has the molecular formula C20 H14 O4. Thus its Mr is (12*20+1*14+16*4) or 318.
Phenolphthalein turns pink when it comes into contact with a basic solution, due to a chemical reaction that changes its molecular structure.
The molecular weight of vanillideneacetone is 192.214g/mol.
The molecular weight of insulin is approximately 5,800 Daltons.
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
When phenolphthalein is added to sulfuric acid, the sulfuric acid causes the phenolphthalein molecule to lose its specific color due to a chemical reaction that alters its molecular structure. This reaction likely involves protonation of the phenolphthalein molecule, leading to a change in its absorption of light and resulting in a colorless solution.
Yes, phenolphthalein is a compound with the molecular formula C20H14O4.
Phenolphthalein turns pink when it comes into contact with a basic solution, due to a chemical reaction that changes its molecular structure.
It has a molecular weight of 21,600 Daltons
molecular structur C9H8K2O4molecular weight: 258.35
To determine the equivalent weight from the molecular weight, you need to divide the molecular weight by the valence (or charge) of the compound. For example, for a compound with a molecular weight of 100 g/mol and a valence of 2, the equivalent weight would be 50 g/equiv.
The molecular weight of vanillideneacetone is 192.214g/mol.
Sodium nitrate molecular weight is 84,9947.
Sodium nitrate molecular weight is 84,9947.
The molecular weight of insulin is approximately 5,800 Daltons.
The weight average molecular weight of the compound is the average of the molecular weights of all the molecules in the sample, weighted by their relative abundance.
The weight average molecular weight of the polymer is the average of the molecular weights of all the polymer chains in the sample, taking into account the weight of each chain.
When phenolphthalein is added to sulfuric acid, the sulfuric acid causes the phenolphthalein molecule to lose its specific color due to a chemical reaction that alters its molecular structure. This reaction likely involves protonation of the phenolphthalein molecule, leading to a change in its absorption of light and resulting in a colorless solution.
