How many liters of 4.0 M NaOH solution will react with 0.30 liters 4.0 M H2SO4?

H2SO4 + NaOH → Na2SO4 + H2O

A. 1.6 L
B. 1.2 L
C. 0.90 L
D. 0.60 L

Answer 1

Answer:

D. 0.60 L.

Explanation:

• For the acid-base neutralization, we have the role:

The no. of millimoles of acid is equal to that of the base at the neutralization.

∴ (XMV) NaOH = (XMV) H₂SO₄.

X is the no. of reproducible H⁺ (for acid) or OH⁻ (for base),

M is the molarity.

V is the volume.

• For NaOH:

X = 1, M = 4.0 M, V = ??? L.

• For H₂SO₄:

X = 2, M = 4.0 M, V = 0.3 L.

∴ V of NaOH = (XMV) H₂SO₄/(XM) NaOH = (2)(4.0 M)(0.3 L)/(1)(4.0 M) = 0.6 L.

So, the right choice is: D. 0.60 L.
