LAB MOD 3 Flashcards
a process in which atleast one substance is produced as a result of chemical change
Chemical reaction
product of ZnS
yellow smoke
product of 2AlI3
violet smoke
factors affecting the rate of solution formation
temperature- directly proportional- S to L
Agitation- directly proportional
Particle and surface area:
size- inversely
surface- directly

water and salt sol
soluble ; polar and polar ionic
alcohol and salt sol
Insoluble; semi polar and polar ionic
Acetone and salt sol
Insoluble; weak polar and polar ionic
water and KAl

polar solvents characteristics
large dipole moment
dissolve polar compounds
partial + and - charge
molecules contain atoms with higher differences in electronegativity
Non polar solvent characteristics
no dipole
dissolve non polar
no charge separation
atoms have nearly similar electronegaticity

miscible; polar polar
water and acetone sol
Miscible; polar and polar
water and oil sol
Immiscible; polar and non polar
ethanol and acetone sol
Miscible; polar and polar
ethanol and oil sol
immiscible; polar and non polar
acetone and oil sol
Immiscible; polar and non polar
