Bases generate Hydroxide (OH - ) ions in water. Bases that dissolve in water are called Alkalis .
An aqueous solution of Sodium Hydroxide will split up into Hydroxide (OH - ) ions along with Sodium Ions (Na + ).
NaOH (aq) → OH - + Na +
When Sodium Hydroxide (Base) is dissolved in water, it produces positive Sodium ions and negative Hydroxide ions. Because of the presence of ions,bases conduct electricity.
