To form ion, this element will loose 3 electrons.
Sulfate ion is a polyatomic ion having chemical formula of
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the chemical formula for Iron (III) sulfate is
Answer :
(A) The number of moles of ions per liter is, 0.1 moles/L
(B) The number of molecules of ion is,
(C) The pH of the solution will be, 4
<u>Solution for part A :</u>
First we have to calculate the pOH of the solution.
As we know that,
Now we have to calculate the moles of ion per liter.
<u>Solution for part B :</u>
First we have to calculate the ion concentration.
Now we have to calculate the number of molecules of ion
As, 1 mole contains number of molecules of
ion
So, moles contains
number of molecules of
ion
<u>Solution for part C :</u>
