ch 8 Flashcards
solvent
greatest amt, usually water
solute
lesser amt
solubility
max amt of solute dissolvable in a set amt of solvent at specific conditions
temp-solubility relationship
higher temp –> lower solubility of gases in water
inverse
henry’s law
higher pressure –> higher solubility of gases in water
proportional
saturated solution
contains max solute that can dissolve
supersat solution
temp. contains more dissolved solution than in sat. – unstable
unsat solution
contains less than in sat. – most common
concentrated
large solute amt
dilute
small solute amt
aqueous
solvent is water
non-aqueous
solvent is not water
solution formulation - how to get uniformly dispersed mixture
- solvent attractive forces need to be overcome (hydrogen bonding)
- solute attractive forces need to be overcome
(ionic)
factors affecting rate of solution formulation
- surface area of solute
- degree of agitation (i.e. stirring)
- temp. (higher temp. –> more molecular mvmt)
solubility rules
