Select the incorrect statement about,
`R-underset(NH_(2))underset(|)(CH)-COOH`
if the following equilibrium exists :

Options

A. `[H^(+)]=sqrt(K_(a_(1))xxK_(a_(2)))`
B. `pH=(pK_(a_(1))+pK_(a_(2)))/(2)`
C. the concentration of `[H^(+)]` for zwitter ion can be calculated for any amphoteric such as `HCO_(3)^(-)`
D. the pH of aqueous solution depends upon concentration of `R-underset(NH_(2))underset(|)(CH)-COOH`

Answer

D

Explanation

The pH of zwitterionic molecules do not dependend upon their concentration.
