Nonionic surfactants are a distinct type of surfactant with an uncharged polar head. In horticultural contexts, nonionic surfactants may be known as wetting agents because they help hydrophobic, or water repelling, soils to quickly and evenly absorb water by breaking the water's surface tension, allowing water molecules to spread for greater and faster water penetration. According to the University of Georgia (UGA), nonionic surfactants are the most popularly used surfactants in the horticulture industry, and though these surfactants can cause damage to plants, they are safe if used in the proper quantity.Know More
As a wetting agent, nonionic surfactants are often mixed in with potting media in order to ensure easy water absorption into plant soil. UGA has also indicated that research is being carried out into nonionic surfactants' efficacy as antifungal treatment.
In addition to application in the horticultural sector, nonionic surfactants can be used, like other surfactants, to create cleaning projects such as detergents. The substance's ability to break water's surface tension is also useful in this application as it allows cleaning water to absorb grease, which is normally repelled from water. In this context, nonionic surfactants such as polyethylene ethoxylate, a nonionic detergent, are used alongside other types of surfactants, including anionic and cationic surfactants.Learn more about Chemistry
Arsenic is a naturally occurring semi-metal element. Its atomic number is 33, and its only stable isotope has an atomic weight of 74.92. Arsenic has been used since ancient times, but it was first isolated by the German chemist Albertus Magnus in 1250.Full Answer >

The critical point of a substance, also known as the critical state, is the temperature and pressure at which the gas and liquid phase of the substance have the same density. At that point, the gas and liquid phases of the substance are indistinguishable from one another.Full Answer >
Minerals are naturally occurring substances that are solid and amorphous. They are described by different physical properties such as crystal structure, luster, hardness, color, fracture and more. Metallic minerals are minerals that contain metallic elements.Full Answer >
