You Have An Unknown Solution Whose Initial Ph Is 2 90 Addition Of 10 Ml Of The Titrant Increased The Ph To 4 15 Adding 1 (13.52 KiB) Viewed 46 times

You have an unknown solution whose initial pH is 2.90. Addition of 10 ml of the titrant increased the pH to 4.15. Adding small-volume increments of the titrant causes the pH to increase very slightly. At equivalence point, the pH of the solution is at 8.70. Abrupt increase in pH to 10.00 was observed when 0.1 ml of titrant was added after equivalence point. Addition of few more drops of the titrant just increase the pH even more with no buffering region. Which among the choices best describes the analyte?
