The pK_(a1) and pK_(a2) of an amino acid are 2.3 and 9.7 respectively. The isoelectric point of the amino acid is:

pK_(a) of a weak acid is defined as :

When a salt reacts with water resulting into formation of acidic or basic solution, the process is referred to as salt hydrolysis. The pH of salt solution can be calculated using the following equations. pH = ( 1)/(2) ( p K_(w) + pK_(a) + log C) for salt of weak acid and strong base. pH = (1)/(2) ( pK_(w)- pK_(b) - log C ) for salt of weak base and strong acid. pH = (1)/(2) ( pK_(w) + pK_(a) - pK_(b)) for salt of weak acid and weak base The pH of 1M PO_(4(aq))^(3-) soluiton will be ( given pK_(b) of PO_(4)^(3-) = 1.62 )

If K_(a) and K_(b) are the dissociation constants of weak acid and its conjugate base , pK_(a) + pK_(b)

Prove that the dergee of dissociation of weak acid is given by: alpha = (1)/(1+10^(pK_(a)-pH)) where K_(a) is its dissociation constant of the weak acid.
