What are \( \left[\mathrm{H}^{+}\right],\left[\mathrm{A}^{-}\right] \)and \( \left[\mathrm{B}^{-}\right] \)in a solution that contains \( 0.03 \mathrm{M} \mathrm{HA} \) and \( 0.1 \mathrm{M} \mathrm{HB} . \mathrm{K}_{\mathrm{a}} \) for \( \mathrm{HA} \) and \( \mathrm{HB} \) are \( 3.0 \times 10^{-4} \) and \( 1.0 \times 10^{-10} \) respectively.
(A) \( \left[\mathrm{H}^{+}\right]=3 \times 10^{-3} \mathrm{M} \)
(B) \( \left[\mathrm{A}^{-}\right]=3 \times 10^{-3} \mathrm{M} \)
(C) \( \left[\mathrm{B}^{-}\right]=3.33 \times 10^{-9} \mathrm{M} \)
(D) All of these
