Answer:

110

Explanation:

Given The conductivity of 0.1 N NaOH solution is 0.022 5 cm . When equal volume of 0.1 N HC solution is

added, the conductivity of resultant solution is decreases to 0.0055 S cm. The equivalent

conductivity in S cm equivalent of NaCl solution is?

We know that NaOH + Hcl gives 2 free electrons.

Now equivalent conductivity

λ = k x 1000 / N , N is normality

= 2 x 0.0055 x 1000 / 0.1

λ = 110 Scm^2eq^-1

So the equivalent conductivity of NaCl solution is 110Scm^2eq^-1
