Deconstructive Practical
visually identify the type and number of compounds
2 liquids 1 solid
precipitate solid and homogeneous liquids
filter through a separating funnel to separate the solid from the liquids
distill the liquids to separate them, identifying
boiling points
with the separated solids and liquids, follow necessary procedures as shown in the 3 solids and 3 liquids branches
dissolved solid and homogeneous liquids
distill the solution to separate the two liquids which will have different
boiling points
test
electrical conductivity
to identify the presence of an
IONIC COMPOUND
distill again both liquids/solutions to separate the liquid from the solid dissolved in one of them
with the separated solids and liquids, follow necessary procedures as shown in the 3 solids and 3 liquids branches
precipitate solid and heterogeneous liquids
filter through a separating funnel to separate all three compounds (as liquids have different
densities
)
with the separated solids and liquids, follow necessary procedures as shown in the 3 solids and 3 liquids branches
dissolved solid and heterogeneous liquids
filter through a separating funnel to separate liquids of different
densities
test
electrical conductivity
to identify the presence of an
IONIC COMPOUND
distill both liquids/solutions to separate the liquid from the solid dissolved in one of them
with the separated solids and liquids, follow necessary procedures as shown in the 3 solids and 3 liquids branches
2 solids 1 liquid
filter through a separating funnel to separate the solids from the liquid
liquid
in case there is something dissolved in the liquid, test
electrical conductivity
to detect the presence of separated charged particle
conducts
follow procedure for 2 liquids, 1 solid
does not conduct
as it is liquid at room temperature, and does not conduct, we can assume it is not an ionic compound or a metallic compound. to test if it is molecular covalent or continuous, we can test physical properties such as
boiling
and
melting/freezing
point
high melting and boiling point
CONTINUOUS COVALENT
low melting and boiling point
MOLECULAR COVALENT
solids
can attempt to dissolve this compound first in water then in other compounds. this will identify
solubility
and, once dissolved, will allow for the testing of
electrical conductivity
does not conduct
as there are separated particles due to the compound being dissolved, a lack of charge indicates a
MOLECULAR COVALENT
compound
conducts
this indicates the presence of charged particles, making the solid an
IONIC COMPOUND
3 liquids
heterogeneous solution
filter through a separating funnel to separate liquids of different densities
if there were only two liquids of different densities separated, this indicates either a solid dissolved in one liquid, or two homogeneous liquids. test
electrical conductivity
to determine the presence of a solid (then follow the 2 liquids 1 solid procedure). however, if no charge is detected, distill the liquids to separate them based on
boiling point
high boiling point
CONTINUOUS COVALENT
low boiling point
MOLECULAR COVALENT
if all three liquids were separated through filtration, begin testing
boiling points
high boiling point
CONTINUOUS COVALENT
low boiling point
MOLECULAR COVALENT
homogeneous solution
a compound of one continuous density indicates either solid(s) dissolved in a liquid(s), or three homogeneous liquids. test
electrical conductivity
to determine the presence of a solid (then follow the 2 liquids 1 solid procedure). however, if no charge is detected, distill the liquids to separate them based on
boiling point
high boiling point
CONTINUOUS COVALENT
low boiling point
MOLECULAR COVALENT
3 solids
magnetic extraction to identify
metallic properties
non-magnetic compound
if there is more than one non-magnetic compound, separate further by attempting to dissolve one of the compounds. this will identify
solubility.
this solution can then be filtered through a separating funnel.
dissolved solute
while it is dissolved in water, this is a prime time to test the
electrical conductivity
of the compound.
conducts
this indicates the presence of charged particles, making the solid an
IONIC COMPOUND
does not conduct
as there are separated particles due to the compound being dissolved, a lack of charge indicates a
MOLECULAR COVALENT
compound
left-over solid
can attempt to dissolve this compound in other compounds. this will identify
solubility
and, once dissolved, will allow for the testing of
electrical conductivity
while it is dissolved, test the
electrical conductivity
of the compound.
