Answer to Question #307089 in Inorganic Chemistry for bran

Question

What is the strength of the ionic interactions between an ion with 1 positive charges and an ion with 1 negative charges, when the distance between them is 16.4 nanometers and the solvent is benzene, with a dielectric constant of 4.6?

Answer 1

E = kq₁q₂ / Dr

k = 9 × 10⁹ N m²/C²

q₁, q₂ - charges

r - distance between the charges

D - dielectric constant

E = 9 × 10⁹ N m²/C² × 1 × 1 / (4.6 × 16.4 × 10^-9 m) = 1.2 × 10¹⁷ N m
