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?

Question

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?

Write the balanced equation before starting the math.

Answer 1

To solve this problem, first write a reaction so you know how many moles of HCl are required per mole of Ba(OH)2. Then, you will use the relationship M1V1=M2V2 (correcting for moles per mole required) to find the missing volume value.
