WebThe freezing point depression osmometer measures the freezing point of the solution to determine its concentration. The freezing point of a solvent lowers when another compound is added. ... the sample must have low viscosity. The accuracy of the test may be impaired if the solution is colloidal or has a high concentration of dissolved ... WebIt is distinct from the freezing point which is the temperature at which the liquid and solid phases of a substance are in equilibrium. In certain cases, this may happen over a range of temperatures. ... The congealing point will be the mean of not less than four consecutive readings that lie within a range of 0.2°C. Share. Tweet.

WebFreezing-point depression is a drop in the minimum temperature at which a substance freezes, caused when a smaller amount of another, ... i.e. substituting a solute for a solvent molecule in the crystal has high enthalpy. In this case, for low solute concentrations, the freezing point depression depends solely on the concentration of solute ... WebAbove the freezing altitude, the temperature of the air is below freezing. Below it, the temperature is above freezing. The profile of this frontier, and its variations, are studied in meteorology, and are used for a variety of … WebApr 21, 2014 · 1 Answer. Ionics compounds have crystal structure. Thus the cations and anions are strongly attached to one another by inter ionic attractive forces. So to break crystal structure more energy is needed. Thus melting point of ionic compound is very high. Ionic compounds are held together by strong electrostatic forces of attraction, due to the ... cshp foundation
