Answer

Brief Explanations:

When an acid or base dissolves in water, it dissociates into ions. Acids release hydrogen - ions (positive) and anions (negative), bases release hydroxide - ions (negative) and cations (positive). So, they break down into a positive and a negative ion.

Answer:

a positive and a negative ion.
