84. Solving a chemistry problem

43. Write the following definitions: electrolytes, electrolytic dissociation and degree of dissociation (α). Which electrolytes, according to the degree of dissociation, are strong, which are weak? Choose which of the substances given in your version are strong and which are weak electrolytes? Give the name of each electrolyte and write its dissociation. For weak polybasic acids and weak polyacid bases, write the stepwise dissociation and expressions for the KD dissociation constant for each step.
HCl, H2SO3, Mg(OH)2, NaOH, K2HPO4, Na2SO4
