Treating navy bean flour with water at 23 °C partitioned 78.3 g/100 g and 21.7 g/100 g of the flour into the insoluble CI and soluble CS fractions, respectively. A chemist would say that the flour is suspended in the water. In a solution the chemical you add is called the solute and the liquid that it dissolves into is called the solvent. The content of various water-soluble vitamins in flour is only 15% to 40% that in whole-wheat. Flour does not mix well with water.

We call substances that dissolve in water soluble. With time and kneading, one can slowly work the water into the flour to create a dough. Both of these are difficult to "whet" -- have poor wettability, so water does not readily mix without some prior preparation - the water will just "run off" of the flour. This is because flour does not dissolve in water. Soluble fiber dissolves in water, and includes plant pectin and gums. A chemist would say that the flour is suspended in the water.
