Question

explain the methods used to determine molecular weight of colloids​

Answer 1

Answer:

Gel permeation chromatography (GPC), osmometry, light scattering, viscometry, cryoscopy, ebulliometry, ultracentrifugation, mass spectrometry, and end-group analysis are just a few of the techniques that can be used to determine MW.

Explanation:

• The formula M=wRTV, where w denotes the colloidal particles, R denotes the solution constant, T denotes the temperature of the colloidal solution, V denotes the volume, and denotes the pressure, can be used to determine the average molecular mass of the colloids.
• A colloid is a mixture made up of two or more substances that are joined physically rather than chemically ( they can be separated ).
• They are a unique kind of mixture where small bits of one component are dispersed throughout another.
• Since cream is composed of minute fat particles suspended in water, it is a colloid.

Answer 2

Gel permeation chromatography (GPC), ight scattering, viscometer, cryoscopy, ebulliometer, ultracentrifugation, mass spectrometry methods used to determine molecular weight of colloids​.

Explanation:

• Molecular weight determination and molecular structure, of molecules can be determined using mass spectrometry.
• With the help of direct infusion method, we can introduce the samples directly to the detector and determine the molecular weight of a known material.
• They provide structural characterization of an unknown sample.
• The formula M=wRTV, is used to find out the molecular weight, where w denotes the colloidal particles, R denotes the solution constant, T denotes the temperature of the colloidal solution, V denotes the volume, and denotes the pressure.
• The mixture which is made up of two or more substances and that are joined physically than chemically.
• It is a unique kind of mixture in which small bits of component are dispersed.
