Answer: The volume of required is 25.0 ml
Explanation:
According to the neutralization law,
where,
= basicity
= 1
= molarity of
solution = 2.00 M
= volume of
solution = 50.0 ml
= acidity of
= 1
= molarity of
solution = 4.00 M
= volume of
solution = ?
Putting in the values we get:
Therefore, volume of required is 25.0 ml
Start by writing the atoms balance:
Now, determine the change of oxidation states:
has oxidation state 0, so each N has to gain 3 electrons to become 
.
That, means that you need 6 electrons to balance the charges, resulting in:
And the answer is 6 mole of electrons.
