Question

If van't Hoff factor of monofluoroacetic acid in water is 1.076. What is it's degree of dissociation?

Options

• 0.924

• 0.76

• 0.538

• 0.076

Answer 1

0.076

Explanation:

i = 1.076

α = ?

\[\ce{CH2FCOOH ⇌ CH2FCOO^- + H^+}\]

∴ n = 2

α = `("i" - 1)/("n" - 1) = (1.076 -1)/(2 - 1)` = 0.076
