Hello!

The balanced molecular equation for the neutralization reaction between HCl and Ba (OH) ₂ is the following:

2HCl (aq) + Ba (OH) ₂ (aq) → BaCl₂ (aq) + 2H₂O (l)

All neutralization reactions between a strong acid (like HCl) and a strong base (like Ba (OH) ₂ yield a salt (BaCl₂) and water. These neutralization reactions are used along with a visual indicator of pH to calculate the concentration of an unknown solution of an acid or base, titrating against a solution of known concentration.

Have a nice day!
