TEA [102]

Answer:

Explanation:

n-factor of NaOH = 1

OH⁻ concentration = Normality of NaOH

= Molarity x n-factor

= 10⁻⁵ x 1

= 10⁻⁵

Now, pOH = -㏒(OH⁻)

pOH = -㏒(10⁻⁵)

pOH = 5

We know pH + pOH = 14

pH = 14 - 5 = 9

∴pH of 10⁻⁵M NaOH is 9

HALOGENS have 7 electrons in their final shell regardless if the total number of atoms. These 7 electrons would be shared between the 's' and 'p' orbital in the form ns² np⁵ (the same as the question). Attached is a table that highlights the fact that halogens have the same form in terms of the valence electrons.
