Low freezing point examples
WebA 0.01-molar solution of Cu(NO 3) 2 will have the lowest freezing point. Dissociation of one molecule of cupric nitrate gives 3 ions. All other solutions gives less number of ions. Hence, the depression in freezing point for cupric nitrate is maximum as it gives maximum number of particles in solution. This results in lowest freezing point. http://www.chemistryexplained.com/Ce-Co/Colligative-Properties.html

WebThe presence of a solute lowers the freezing point of a solution relative to that of the pure solvent. For example, pure water freezes at 0°C (32°F); if one dissolves 10 grams (0.35 ounces) of sodium chloride (table salt) in 100 grams (3.53 ounces) of water, the freezing point goes down to −5.9°C (21.4°F). WebSo, if you have 5 moles of sugar (which equals 1711.5 grams of sugar in 1 kg of water) dissolved in water, we can determine the new freezing point as long as we know the …
WebSupercooling, also known as undercooling, is the process of lowering the temperature of a liquid below its freezing point without it becoming a solid. It achieves this in the absence of a seed crystal or nucleus around which a crystal structure can form. The supercooling of water can be achieved without any special techniques other than chemical … WebAn aqueous solution has a higher boiling point and a lower freezing point than does pure water.
