1.Diprotic acid release two H⁺ ions whereas triprotic acid release three H⁺ ions.
2. Suppose the formula of triprotic acid is H3A.
Ionization equations:
H₃A + H₂O ⇄ H₂A⁻ + H₃O⁺
H₂A⁻ + H₂O ⇄ HA²⁻ + H₃O⁺
HA²⁻ + H₂O ⇄ A³⁻ + H₃O⁺
3. Indicator is used to locate the end point in traditional titration. But, no need to use an indicator in pH titration because sudden pH change indicate the end point.
4. Equivalence point is the point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution.
5. pKa is negative log of Ka. The pKa-values of the amino acid are decided from the overall titration graph. To determine pKa1 and pKa2, find the extent on the graphs 1/2 manner between the 2 equivalence factor volumes determined from the accelerated spinoff curves. The pH at this factor is in the titration is equal to pKa2.

Answer:
No, there is no evidence or proof that proves the scientific theory. Therefore, the statement is not a scientific theory.
