HELP In a neutralization reaction, aqueous HCl and aqueous Ba(OH)2 react to form aqueous BaCl2 and water. What volume of 1.50 M HCl will completely neutralize 35.0 mL of 0.520 M Ba(OH)2?

The volume of HCl = 24.27 ml

Reaction

2HCl + Ba(OH)₂ ⇒ BaCl₂ +2 H₂O

mol of Ba(OH)₂ = V x M

From the equation, the mol ratio of HCl : Ba(OH)₂ = 2 : 1, so mol HCl :

So the volume of HCl :

Or you can use the titration formula :

M₁V₁n₁=M₂V₂n₂(n HCl=1, n Ba(OH)₂=2) :
