Which Statement Is FALSE Regarding the Titration of a Dibasic

question 12

Multiple Choice

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.
