The active ingredient in many commercial antifreezes is ethylene glycol (C2H6O2). If you wish to protect your radiator down to –25°F, how many grams of ethylene glycol should you add to each liter of water? First convert the temperature to degrees Celsius, use the Kfvalue of 1.853°C/molal for water, and recall that the density of water is 1.00 g/mL. ` ` Adding a solute to a pure solvent not only causes a decrease in the freezing point of the result- ing solution, it also causes an increase in the boiling point of the resulting solution compared to the pure solvent. Thus, ethylene glycol also protects your radiator from boiling over in hot summer months. Using the antifreeze solution prepared in question 2 above, calculate the boiling point of the solution in degrees Fahrenheit. Use the following equation: ΔTb= (Kb) x (molalitysolution) where Kb= 0.52°C/molal Note: ΔTb = BP solution - BP solvent H2O
