Experimental Methods and Procedures in Monolayers
When a very small amount of a virtually insoluble and nonvolatile organic substance is carefully placed on the surface of water, which has a relatively high surface tension, either of the following results may be observed: (1) The substance may remain as a compact drop (or as a solid mass), leaving the rest of the liquid surface clean, or (2) it may spread out over the entire available surface of the water. The formation of a stable monolayer by any substance is determined by the interactive forces between that substance and the subphase, water.
