What causes phenolphthalein to turn pink?
Phenolphthalein turns pink when it comes into contact with a basic solution, due to a chemical reaction that changes its molecular structure.
What is the molecular weight of vanillideneacetone?
The molecular weight of vanillideneacetone is 192.214g/mol.
WHY DOES PHENOLPHTHALENE TURNS COLORLESS WHEN ADDED BY SULFURIC ACID?
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.
What is molecular weight of insulin?
The molecular weight of insulin is approximately 5,800 Daltons.
What is the weight average molecular weight of the compound in question?
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.
Is phenolphthalein a compound?

What causes phenolphthalein to turn pink?
Phenolphthalein turns pink when it comes into contact with a basic solution, due to a chemical reaction that changes its molecular structure.
Can phenolphthalein pass through a dialysis tubing?
Yes, phenolphthalein can pass through dialysis tubing, as it is a small organic molecule. Dialysis tubing is designed to allow the passage of small solutes while retaining larger molecules, so substances like phenolphthalein, which has a molecular weight of about 318 g/mol, can diffuse through the pores of the tubing. This property is often utilized in experiments to demonstrate diffusion and the selective permeability of membranes.
What is the molecular weight of chymotrypsin?
It has a molecular weight of 21,600 Daltons
What is the molecular weight and molecular formula of potassium humate?
molecular structur C9H8K2O4molecular weight: 258.35
If you have molecular weight how can you find equivalent weight?
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.
