solutions
Molecules with O-H and N-H bonds participate in
hydrogen bonding and interact well with water/are
hydrophilic
vs.
Molecules that have nearly non-polar C-H bonds
that don't participate in hydrogen bonding interact
poorly with water and are hydrophobic - answer
What kind of molecules interact well with water
and are hydrophilic vs. what kind of molecules
interact poorly with water and are hydrophobic?
hydrocarbons are a class of molecules that are
hydrophobic - answer Are hydrocarbons
hydrophobic or hydrophilic
Sucrose is hydrophilic - answer Is sucrose
hydrophilic or hydrophobic?
, hydrophobic - answer Are fats hydrophobic or
hydrophilic?
hydrophobic - answer Are alcohol's with long
hydrocarbons chains hydrophobic or hydrophilic?
when two liquids are infinitely soluble in each
other, they're miscible - answer miscible
a material that produces ions when dissolved in
water - answer define electrolyte
substances that dissolve in water as molecules
rather than ions - answer non-electrolyte
strong: all materials go to form ions/ completely
dissociates to ions
vs.
weak: some material forms ions, some remain
neutral - answer strong electrolyte vs. weak
electrolyte
ionic compounds are strong electrolytes and
covalent compounds are non-electrolytes - answer
ionic compounds vs. covalent compounds
(electrolytes?)
