In a titration of 35.00 mL of 0.737 M H\(_2\)SO\(_4\), how many mL of a 0.827 M KOH solution is required for neutralization?

Options:
A. 25.8
B. 62.4
C. 39.3
D. 1.12
E. 35.0

Answer :

For neutralization in a titration of 35.00 mL of 0.737 M H₂SO₄, 62.4 mL of a 0.827 M KOH solution is needed.

H₂SO₄ + 2 KOH ---> K₂SO₄+ 2 H₂O

from the concentration equation

m1 n1 v1 = m2 n2 v2 ( since m = molarity , n = factor and v = volume)

M1 = 0.737 M

n1 = 2

V1 = 35 mL

M2 = 0.827 M

n2 = 1

V2 = ??

0.737 m x 2 x 35 mL = 0.827 m x 1 x v2

v2 =62.4

Hence, 62.4 mL of a 0.827 M KOH solution is needed for neutralization.
