How Do We Determine the Position of Equilibrium in an Acid-Base Reaction

4 How Do We Determine the Position of Equilibrium in an Acid-Base Reaction  

Vinegar (which contains acetic acid) and baking soda (sodium bicarbonate) react to produce sodium acetate, carbon dioxide, and water. The carbon dioxide inflates the balloon. 

We know that HCl reacts with HgO according to the following equilibrium  

We also know that HCl is a strong acid, which means that the position of this equilibrium lies very far to the right.
