Which statement is FALSE regarding the titration of a dibasic weak base with a strong acid? B + H⁺ → BH⁺ BH⁺ + H⁺ → BH₂²⁺ A)For V = 0,the pH is dictated by the reaction of B with H₂O. B)Before the first equivalence point,V_eq1 the buffer created by B and BH⁺ determines the pH. C)At V_eq1 the pH is due to the reaction of BH⁺ with H₂O. D)After the first equivalence point,V_eq1 and before the second equivalence point,V_eq2,the buffer created by BH⁺ and BH₂²⁺ determines the pH. E)At V_eq2 the pH is due to the reaction of BH₂²⁺ with H₂O.

At the first equivalence point, the pH is not determined by the reaction of BH⁺ with water (H₂O), but rather by the complete neutralization of the first acidic hydrogen, leaving behind the weakly basic species BH⁺ in solution, which partially ionizes in water to establish the pH.
