Sentence Examples


  • On cooling a saturated solution to - 10°, or by cooling a solution in hot hydrochloric acid, the hydrate NaCI.2H 2 O separates; on further cooling an aqueous solution to - 20° a cryohydrate containing 23.7% of the salt is deposited.
  • If, on the other hand, the salt of the cryohydrate fails before the ice the water given by the continued fusion dilutes the solution, and we pass along the curve OB which shows the freezing points of a series of solutions of constantly increasing dilution.
  • Thus in interpreting complicated freezing point curves, we must look for chemical compounds where the curve shows a maximum, and for a eutectic or cryohydrate where two curves meet at a minimum point.
