115. Solving a chemistry problem
Content: 25.rar 23,82 kB
Product description
25. Solutions of 2 electrolytes are considered, the molar concentration of each of which is equal to See. 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 KKnAm
Determine the pH value of strong and weak electrolyte solutions.
Numerical values of Cm and KKnAm: Cm=0.0001 mol/l; KKnAm \u003d 5 * 10-8.
Electrolytes: [Cd(NH3)6](OH)2 and HClO.
