A30.00 ml ba(oh)2 solution of unknown concentration was neutralized by the addition of 32.83 ml of a 0.1382 m hcl solution. write the balanced molecular equation for the neutralization reaction between hcl and ba(oh)2 in aqueous solution. include physical states.

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!
