WebOct 27, 2024 · Assuming complete dissociation, a 1.0 m aqueous solution of NaCl contains 2.0 mole of ions (1.0 mol Na + and 1.0 mol Cl −) per each kilogram of water, and its freezing point depression is expected to be. When this solution is actually prepared and its freezing point depression measured, however, a value of 3.4 °C is obtained. WebAlternatively, a conversion factor could be derived for the calculation: The required quantities of low- and high-concentration solutions can then simply be obtained by multiplying their quantities obtained by the alliga-tion formula by this factor. Thus, the quantity of 40% w/v solution required = 7 × 5.714 = 39.998 = 40 mL.
