Question

Virat studies the solution formed by dipping two drops of Dettol in water and notes the properties of the solution formed.​

Answer 1

Answer:

Correct option is

D

0.080 N

Explanation:

It is given that a solution is formed by diluting 250 mL of 0.4 N H2​SO4​ with one litre of water.

N1​=0.4 N

V1​=250 mL

On adding 1L of water, the new volume V2​= 250 mL + 1000 mL = 1250 mL.

Let the Normality of above-formed solution be N2​.

We know that, N1​×V1​=N2​×V2​

                       0.4×250=N2​×1250

                     

                       N2​=1250100​

                   

                       N2​=0.08N

Hence, the correct option is (D).
