Answer to Question #223321 in Inorganic Chemistry for Rashinda mz

Question

The electronic configuration of an atom's valence shell is ns²np². During the titration of a CuCl₂ with conc. H₂SO₄(0.1M) acid and a suitable indicator was used such that P^H(y) of the HCl was 1.500. What is the period to which the element belongs with respect to the fact that y= -log(10+10^n/2)

Answer 1

Y= log (10+10^1.5/2)

Y= log (10+10^0.75)

Y= log (10+5.62)

Y= log 15.62= 1.19

Hence belongs to period 1
