WebJul 16, 2013 · Hydrophilic and hydrophobic materials are defined by the geometry of water on a flat surface — specifically, the angle between a droplet’s edge and the surface underneath it. This is called the contact angle. If the droplet spreads, wetting a large area of the surface, then the contact angle is less than 90 degrees and that surface is ... WebThe upper few inches of soil are often hydrophilic. Mix up water-detergent solutions for each of the three detergent formulations. Use the same amount of water and detergent in …
