Solutions Flashcards
What is the electrostatic interaction between solute & solvent molecules known as ?
Solvation/dissolution
*When H2O is solvent = hydration
The max amount of solute than can be dissolved in a solvent given the temp is referred to as ?
Solubility
What are 2 solubility rules that are absolutes ?
- All salts containing NH4+ & alkali metals (group 1) are water-soluble
- All salts containing NO3- (nitrate) & CH3COO- (acetate) anions are H2O soluble
A molecule in which a cation is bonded to @ least one e- pair donor is known as ?
Complex ion/coordination compound
- Ligands: e- pair donor molecules
- Held together by coordinate covalent bonds: e- pair donor (lewis base) & e- pair acceptor (lewis acid) form stable compound
A central cation being bonded to the same ligand in multiple places is known as ?
Chelation
The amount of solute dissolved in a solvent is a measure of what ?
Concentration
What do representations of brackets in concentration demonstrate ?
Molarity
The # of equivalents of interest per liter of solution is known as ?
Normality
If IP < Ksp, then…?
Solution not yet @ equilibrium = unsaturated (dilute)
If IP > Ksp, then…?
Solution is beyond equilibrium = supersaturated
The molarity of a solute in a saturated solution is called the ?
Molar solubility
What is the difference between Ksp & Kf ?
Ksp is the dissolution of the original solution, & Kf is the subsequent formation of the complex ion
Vapor pressure depression caused by solutes in solution is based on what ?
Raoult’s Law
- As solute is added to solvent, vapor pressure decreases proportionally
- Ideal solutions
The # of particles a a compound dissociates into corresponds w/ what ?
van’t Hoff factor
