if ionisation constant of an acid HA at equilibrium is 1.0 * 10^ 8, then calculate the value of pKa and pKb (for its conjugate base )
![SOLVED: A diprotic weak base (B) has pKb values of 4.933 (pKb1) and 8.633 (pKb2). Calculate the fraction of the weak base in each of its three forms (B, BH , BH22 ) SOLVED: A diprotic weak base (B) has pKb values of 4.933 (pKb1) and 8.633 (pKb2).
