buffer
resists to change in PH levels
solute
the substance being dissolved (less amount than solvent)
solvent
the medium used for dissolving (more than the solute)
electrolyte
ion in solution that conducts electricity soluble ionics
strong acid
acid that completely dislocates in H2O, strong electrolyte
HCl, H2SO4, HNO3
weak acid
acid that partially dissolves in H2O, weak electrolyte, (HC2H3O2)
strong base
base that completely dissociates in h2o, strong electrolye,
NaOH, LiOH, KOH
weak base
base that partially dissociates in h20, weak electrolyte (NH3)
saturated solution
maximum amount of solute dissolved at a given temperate
unsaturated solution
less than maximum amount of solute dissolved at a given temperature
supersaturated solution
more than the maximum amount of solute dissolved at a given temperature
factors affecting dissolving rates of solids and gases
for solids: Temp-up solubility-up
for gases: temp-up solubility-down
surface area: surface area-up rate for gas+liquid-up
stirring: stirring-up rate-up
electrolytes (3 kinds)
non: don’t produce an electrical current in solution. Do not form ions. No light bulb.
weak: produces some ions in solution. Weak acid-Vinegar(HC2H3O2) weak base ammonia. Half light bulb.
strong: produce large amount of ions in solutions. Most ions compounds that are soluble in H2O: NaCl, NaHCO3, strong acid: HCL. Whole Light bulb.
