LIFE 102 Lecture Notes - Lecture 3: Molar Concentration, Ionic Compound, Hydronium
Document Summary
When an ionic compound is dissolved in water, each ion is surrounded by a sphere of water molecules called a hydration shell. *water can dissolve compounds made of nonionic polar molecules. *large, polar molecules can dissolve in water if they have ionic and polar regions. One that does not have a love for water. Stable suspension of fine particles in a liquid. The sum of all masses of all atoms in a molecule. The number of moles of solute per liter of solution. A hydrogen atom in a hydrogen bond between two water molecules can shift from one to the other. Hydrogen atom leaves its electron behind and is transferred as a proton (aka hydrogen ion) The molecule that lost the hydrogen ion (proton) Concentrations of h+ and oh- are equal in pure water. Adding acids and bases modifies the concentration of h+ and oh- Defined by the negative logarithm of h+ concentration.
