WebWater molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution. Find out more Adhesion/cohesion WebEach water molecule can form 4 hydrogen bonds. Distinguish between cohesion and adhesion. Cohesion is the phenomenon of the collective hydrogen bonds holding water together. Adhesion, however, is the clinging of one substance to another. ... It does so by accepting hydrogen ions from the solution when they are in excess and donating …

WebHydrogen bonds are common, and water molecules in particular form lots of them. Individual hydrogen bonds are weak and easily broken, but many hydrogen bonds together can be very strong. London dispersion forces Like hydrogen bonds, London dispersion forces are weak attractions between molecules. WebJun 11, 2024 · 1 Answer. Sorted by: 6. Hydrogen does form ionic bonds. Although not as bare H X +, it can form ionic bonds in the form of H X − ( hydride anion ). H X − forms … WebTo answer the first question, a molecule must have a charge to dissolve in water, because for a substance to dissolve, it has to form bonds with the solvent, and it cant do that unless it is polar 2. It happens with polar … how does a blood pressure pill work
