Question

How many milliliters of a 0.221 M HCl solution are needed to neutralize 299 mL of a 0.0459 M Ba(OH)2 solution?

Answer #1

**ANSWER:**

Given,

Molarity of HCl , M_{1} = 0.221 M

Normality of HNO_{3}, N_{1} = 0.221 M {because
it releases 1 H^{+} only}

Volume of HCl, V_{1} = ?

Molarity of Ba(OH)_{2}, M_{2} = 0.0459 M

Normality of Ba(OH)_{2}, N_{2} = 2 x
M_{2} {because it releases 2 OH^{-}}

= 2 x 0.0459 = 0.0918 N

Volume of Ba(OH)_{2}, V_{2} = 299 mL

Now, at neutralization point:

N_{1} x V_{1} =
N_{2} x V_{2}

0.221 N x V_{1} = 0.0918 N x
299 mL

V_{1} = 124.2 mL

**Hence, 124.2 mL of a 0.221 M HCl solution are needed to
neutralize 299 mL of a 0.0459 M Ba(OH)2 solution.**
