Question

How the abnormal molecular masses can be corrected

Answer 1

Molecular masses of the solute can be easily determined with the help of colligative properties; relative lowering in vapour pressure, boiling point elevation, freezing point depression, and osmotic pressure easily. But, we derived the relation between the molecular mass of solute and colligative properties under some assumptions, which are:The solution is diluted that is, solvent is available in large amount in order to obey Raoult’s LawThe solute neither went dissociation or association in the solutionSo, how do we determine the molecular mass of solute in case the above assumptions are not valid? Basically, the abnormality is due to:Association of Solute ParticlesDissociation of Solute Particles

Answer 2

To fix the molecular mass in some circumstances, abnormal molecules may need to undergo chemical alteration. This may entail altering the molecule's structure or adding or deleting chemical groups.

• Depending on what caused the abnormality, there are many ways to rectify abnormal molecular masses. Using chromatography, a method that separates molecules according to their shape and characteristics is one strategy. By separating the abnormal molecules from the normal ones using this technique, the anomaly may be recognized and fixed. A different strategy is to employ electrophoresis, which divides molecules according to their charge and size and enables the identification and repair of anomalies.

• Mass spectrometry is a different strategy that can precisely ascertain a molecule's molecular mass and spot any anomalies. Corrective actions can be made to return the molecular mass to normal levels after the problem has been recognized. Overall, to rectify abnormal molecular masses, a variety of procedures may be required.
