We intend to divulge an easy experiment that permits the determination of molar masses of various compounds by cryoscopy. The major advantage of this is the use of the tert-butyl alcohol as a solvent, which requires simple apparatus and easy procedures. The melting point of this alcohol is ...

It was chosen three polymers of the polyacrylamidetype, which differ in molar weight and charge density. It was studied the addition of thesepolymers in relatively small concentration 0,1% in mass and maximum concentration of2,0%. It was made analysis of flow to determine the appearing ...
