Is kf molecular
WitrynaConsider the equation for freezing point depression. ΔTf = KfM. Where m = mol (solute)/kg (solvent) And we know Molar mass = g/mol. Rearranging the above equation: M = ΔTf / Kf …equation 1. Where, ΔTf = freezing point and Kf = freezing constant. ΔTf = 5.46 degrees Celsius- 3.98 degrees Celsius = 148 degrees Celsius. Karl Fischer titration is a classic titration method in chemical analysis that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator.
