A25-ml solution of h2so4 is completely neutralized by 18 ml of 1.0m naoh. what is the concentration of the h2so4?
h2so4(aq) +2naoh(aq) _ na2so4(aq) + 2h2o(l)

a.0.72m
b.0.009m
c.0.50m
d.0.36m

Answer : The correct option is, (D) 0.36 M

Explanation :

Using neutralization law,

where,

= basicity of an acid = 2

= acidity of a base = 1

= concentration of = ?

= concentration of NaOH = 1.0 M

= volume of = 25 ml

= volume of NaOH = 18 ml

Now put all the given values in the above law, we get the concentration of the .

Therefore, the concentration of the is, 0.36 M

6.4 cm (max) - 25 cm (min)
