The concentration of all species in a 0.100 M solution has to be calculated
Acid ionization constant :
The equilibrium expression for the reaction is given below.
Where is acid ionization constant, is concentration of hydrogen ion, is concentration of acid anion, is concentration of the acid
Diprotic and polyprotic acids:
Acids having two or more hydrogen atoms are termed as diprotic or polyprotic acids. These acids lose one proton at a time by undergoing successive ionizations.
For diprotic acids, the successive ionization constants are designated as
For triprotic acids, the successive ionization constants are designated as
