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.
