Answer:
B) HA⁻ and Li⁺ A²⁻ and Li⁺
Explanation:
Titration of acid H₂A with LiOH solution.
At first equivalent point
H₂A + LiOH → HA⁻ + Li⁺ + H₂O
Main component at (EP1) => HA⁻ and Li⁺
At second equivalence point
HA⁻ + LiOH → A²⁻ + Li⁺ + H₂O
Main component at (EP2) => A²⁻ and Li⁺
Therefore, the correct answer is B
