Current Question (ID: 8454)

Question:

$\text{The oxoacid that has the highest } K_a \text{ value is:}$

Options:

1. $\text{HClO}_3$
2. $\text{HBrO}_3$
3. $\text{HIO}_3$
4. $\text{All have equal } K_a$

Solution:

$\text{Hint: Down the group oxoacid of halogen acidity decreases.}$ $\text{Cl, Br, I all belong to the same group. As one goes down the group, the atomic size increases, and electronegativity decreases. Electronegativity is the ability of an atom to pull electrons towards itself.}$ $\text{Acid strength order:}$ $\text{HClO}_3 > \text{HBrO}_3 > \text{HIO}_3$ $\text{Stability of their conjugates:}$ $\text{ClO}_3^- > \text{BrO}_3^- > \text{IO}_3^-$
