Soap dissolves in water. A soap molecule has a long hydrocarbon End and a short ionic end containing COONa+.The non-ionic hydrocarbon end has the property to repel water. (hydrophobic tail). The ionic end has the property to attract water. This end attaches itself to water.(hydrophilic head). The hydrocarbon end attaches to the dirt or grease to form structures called ‘micelles’
