Consider the hydrate below.
FeCl3•6H2O
Which part of the formula comes first in the name of the
compound?
Solution :-
the formula given is FeCl3.6H2O
the name for the formula is Iron (lll) chloride hexahydrate.
hexahydrate means it contains 6 moles of water
we start writing the name with writing the name of the metal
the part which comes first in the name is the FeCl3 name that is iron (lll) chloride
and then 6H2O is written as hexahydrate
so the complete name is Iron (lll) chloride hexahydrate
