INTERACTIONS OF INORGANIC SALTS WITH GELATIN

The interaction of ammonium chloride and magnesium sulphate on gelatin , a high molecular protein is studied. Various salt concentrations (0. 25-4 M) were allowed to interact with gelatin solution. The ultrasonic velocity is high in salt solution than in the mixtures. In pure salt the velocity increases linearly with concentration. Other parameters l ike, adiabatic compressibility, free length, free volume, internal pre ssure, molar sound velocity and molar compressibility are presented. T he molar compressibility is very high in mixtures than in the salt sol ution. It is observed that the interaction between ammonium chloride a nd gelatin is mote than that of magnesium sulphate and gelatin.
