What is the ionic form of the
chemical expression CuSO4 aqueous?
We can see that the state symbol in
this chemical expression is aq or aqueous, meaning that this substance is dissolved
in water. When ionic substances are dissolved
in water, they break apart into the positive and negatively charged ions that make
them up. So if we want to create the ionic
form for the expression CuSO4 aqueous, we need to figure out what ions CuSO4 is made
of. Well, Cu is the symbol for
copper. Copper forms positively charged
ions, but it can form ions of multiple different charges. So we’ll need to figure out what
its charge is by looking at the other ion in this expression.
SO4 is the polyatomic ion sulphate,
which has the charge two minus. So that means in order for this
compound to have an overall neutral charge, copper must have a charge of two plus,
meaning that this compound is copper(II) sulfate. Of course, we shouldn’t forget our
state symbols since these ions are still in water. So the ionic form of the chemical
expression CuSO4 aqueous is Cu2+ aqueous plus SO42− aqueous.
