WebDec 24, 2014 · Water has a network of hydrogen bonds between molecules in its liquid phase and so when a substance dissolves in water this bonding is disrupted. However, acetic acid is able to form many new hydrogen bonds to water molecules and so this results in a highly favourable interaction, leading to the high solubility of acetic acid in water. Share Webcovalent molecules dissolve in water, they do not ionize or separate into smaller particles like ionic compounds do. Compounds bound together with nonpolar covalent bonds tend to be hydrophobic and do not dissolve readily in water. This is because there are no charged or polar parts to interact with the polar water molecules. how many ravens does odin haveWebWater dissolves many other ionic compounds in the same way that it dissolves NaCl. Thus, the water molecules cannot pull the ions apart. WATER AND POLAR MOLECULAR COMPOUNDS.
