CHEM 111 Lecture Notes - Sodium Chloride, Ionic Compound
Document Summary
You have two, one-liter containers each filled with a different gas. These containers are connected via a closed port. There are 0. 25 moles of gas a at a pressure of 0. 30 atm in one container, and there are 0. 50 moles of gas b at a pressure of 0. 60 atm in the other. To dissolve an ionic compound means the strong ionic forces must be broken. Water molecules will rearrange themselves for many ion-dipole interactions, which break apart the ions. Each ion then has a shell of water molecules in solution. Ion-dipole interactions not as strong as ionic bonds. Units vary amount of solute / volume of solution. Indicates maximum amount of material that will dissolve. Nacl in h2o at 20 c = 365 g / l. Nacco3 in h2o at 20 c = 100 g / l. Maximum amount that will dissolve in solution is saturated. Nacl (s) h2o na+ (aq) + cl- (aq)
