The freezing issue of pure h2o is 0 °C. Almost every other substances dissolved within the h2o will decreased the freezing position. When inorganic salts are current, it may be substantially reduce. If a weak Resolution is frozen, pure ice will at first separate, thereby raising the concentration from the dissolved material inside the residual Alternative (further more lessening the freezing place).
