(A) The ionic product of water at 100∘C is 51.3×10−14. So, this statement is incorrect.
(B) On increasing the temperature, pH of solution also decreases.
(C) Since, Na2HPO4 is a salt of strong base NaOH and weak acid H3PO4, it gives a basic solution on hydrolysis.
(D) NH3 can act as both Bronsted acid and base because it can accept H+ion to form NH4+and donate H+ion to form NH2−.
Hence statements B, C, D are correct.
