Abstract
IT is peculiarly difficult to dry certain substances and to determine the water in them because (a) if liquids they may form inconvenient mixtures of constant boiling point (azeotropic) with water, (b) if solids they may retain water of crystallization, form syrups, or be susceptible to oxidation, or (c) their structure and colloidal state may hinder the loss of water, as in wood, peat, etc. One well-known method is to distil after adding a liquid immiscible with water ; the distillate settles into two layers and the volume of water is measured.
