The correct structure of histidine in a strongly acidic solution (pH = 2) is - HR-ÇH-C08 o Examp; NH

Which of the following is correct structure of histidine at pH=0?

An aqueous solution of Be(NO_3)_2 is strongly acidic. Explain.

The pH of an acidic buffer solution & a basic buffer solution at 25^(@)C is :

Statement 1 : In strongly acidic solutions, aniline becomes more reactive towards electrophilic reagents Statement 2 : The amino group is protonated in strongly acidic solution, and thus the lone pair of electron on the nitrogen is no longer available for resonance.
