"
Explanation:
When
is added in the chemical equation it reacts with sodium acetate so, it will give the following chemical equation:
In this, the
is a weak acid so, it not completely dissociated.
were strong electrolytes they are completely dissociated.
The
is a strong acid so, it is completely dissociated So, the net ionic equation is:

Answer:
c it does not change the energy state
