Find freezing point
WebLiquids have a characteristic temperature at which they turn into solids, known as their freezing point. In theory, the melting point of a solid should be the same as the freezing point of the liquid. In practice, small … WebSep 7, 2024 · The freezing point of solution 8.1g HBr in 100g of H2O assuming the acid to be 90% ionized is -0.186 degree centigrade. How do you find the freezing point depression on a graph? freezing point of the solution is determined from the graph by drawing two straight lines through the data points above and below the freezing point.
