Question

Which type of ions form micelle in case of $RS{O}_{4}Na$?

• A. $RS{O}_4^{2-}$
• B. $RS{O}_4^{-}$
• C. $RS{O}_{4}Na$
• D. $R^{+}$

Answer 1

The correct option is B $RS{O}_4^{-}$

$RS{O}_{4}Na\to RS{O}_4^{-}N{a}^{+}$
$RS{O}_4^{-}$ has hydrophobic $\left(R\right)$ and hydrophilic $\left(S{O}_4^{-}\right)$ moities.
