Gavin Mccann · Answer 1

100 mL is the volume of HCl needed to neutralize the 44.3 of Ba (OH) ₂

Explanation:

This is the chemical equation:

2HCl + Ba (OH) ₂ → BaCl₂ + 2H₂O

Formula for neutralization is:

Molarity of acid. Volume of acid = Molarity of base. Volume of base

0.121. Volume of acid = 0.274. 44.3

Volume of acid = (0.274. 44.3) / 0.121 → 100
