<h3>What are ions?</h3>
Ion, any atom or group of atoms that bears one or more positive or negative electrical charges. Positively charged ions are called cations; negatively charged ions, anions.
Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms.
Examples of these processes include the reaction of a sodium atom with a chlorine atom to form a sodium cation and a chloride anion; the addition of a hydrogen cation to an ammonia molecule to form an ammonium cation; and the dissociation of a water molecule to form a hydrogen cation and a hydroxide anion.
Sulphuric (sulfuric) acid is a diprotic acid. When one mole of molecules dissolve in water, two moles of ions would be produced.
.
On the other hand, sodium hydroxide is a monoprotic base. When one mole of formula units dissolve in water, only one mole of hydroxide ions would be produced.

Note that and react at a one-to-one ratio:
.
As a result, it would take of to react with the of that was released when of is dissolved in water. Since one mole of formula units could produce only one mole of , it would take of formula units to produce that of for reacting with of .
