WebIce beer is a beer that has undergone some degree of freezing during production. These beers generally have a higher alcohol content, and lower price relative to it. The process of "icing" beer involves lowering the temperature until ice crystals form. Since ethanol has a much lower freezing point (-114 °C; -173.2 °F) than water (0 °C; 32 °F), when the ice is … WebThe freezing point of a 0.21 m aqueous solution of H2SO4 is -0.796C. (a) What is i?

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.
