The concentration of Iron in the galvanic (voltaic) cell Fe(s) + Mn²⁺(aq) ⟶ Fe²⁺(aq) + Mn(s) is 0.02297 M.
<h3>What is the Nernst Equation?</h3>The Nernst equation enables us to identify the cell potential(voltage) in presence of non-standard conditions in a galvanic cell. It can be expressed by using the formula:
where;
- n = Number of electrons = 2
= Initial voltage = 0.77 V
= Cell voltage = 0.78 V
= Manganese concentration = 0.050 M
Replacing the values into the above equation, we have:

The <em>effective nuclear charge</em> is the difference between the atomic number an element and the shielding constant. Hence, the atom which experiences the greatest nuclear charge is Sulphur, S.
<u>Calculating the greatest effective nuclear charge</u>, :
- Z = Atomic number ; S = shielding constant
<u>For Magnesium, Mg</u>:
Z = 12
S = 10
<u>For Aluminium, Al</u>:
Z = 13
S = 10
For Sulphur, , S:
Z = 16
S = 10
Therefore, the atom whuch experience the greatest is Sulphur.
