21. Solutions of 2 electrolytes are considered, the molar concentration of each of which is equal to C-M. Determine the strength of electrolytes and write down the equations of their dissociation. Name the electrolytes (see counter, work No. 1).
For a strong electrolyte, determine the molar concentration of each ion, assuming that it dissociates completely.
For a weak electrolyte, write down the expression for the dissociation constant and determine the value of the degree of dissociation α if the value of its dissociation constant is equal to KKnAm.
Determine the pH value of strong and weak electrolyte solutions.
Numerical values ​​of С¬M and KKnAm: Сm=0.1 mol/l; KKnAm = 7.5*10-10.
Electrolytes: [Zn(NH3)4](OH)2 and HBO2.
