In this question, we need to write the complete and balanced equation between acetic acid and sodium hydroxide, this reaction must also be written in the net ionic equation at the end:
1. Regarding only with the name of the reactants and products:
Acetic acid + Sodium hydroxide --> Sodium acetate + water
2. Now we balance the equation with the chemical formulas:
CH3COOH + NaOH --> NaCH3COO + H2O
3. Now we write the net ionic equation for this reaction:
To do that, we need to write the physical state of each compound and also to split the strong electrolytes into ions, forming the complete ionic equation
CH3COOH (aq) + Na^+ (aq) + OH^- (aq) ---> Na^+ (aq) + CH3COO^- (aq) + H2O (l)
The net ionic equation must have the ions that have a direct change either in its charge or physical state, and in our reaction, CH3COOH and OH had a change in their charge, therefore the net ionic equation will be:
CH3COOH + OH- --> CH3COO- + H2O
