Disodium tartrate is used in Karl Fischer titration as a secondary standard for calibration. It is stable, easily soluble in water, and provides a known moisture content for accurate calibration of the Karl Fischer reagent. It is useful for verifying the accuracy and reliability of the Karl Fischer titration method.
The relationship between Kf and KB is that they are reciprocals of each other. Mathematically, Kf = 1/KB. This means that if Kf is large, then KB will be small and vice versa.
The Kf value of a solvent can be determined experimentally by measuring its freezing point depression when a known amount of solute is added. The formula used is ΔTf = Kf * m, where ΔTf is the depression in freezing point, Kf is the cryoscopic constant for the solvent, and m is the molality of the solution. By rearranging this formula, Kf can be calculated by Kf = ΔTf / m.
The molar mass of KF is 58.1 g/mol. Given that there are 116 grams of KF in the solution, this corresponds to 2 moles of KF. Therefore, the molarity of the solution is 2 M.
The molar mass of KF is approximately 58.10 g/mol. To calculate the molarity, divide the given mass of KF (116 g) by its molar mass to get moles, then divide by the volume (1.00 L) to get the molarity. The molarity of the KF solution is approximately 2.00 M.
