69. Solving a chemistry problem
Content: 36.rar 29,9 kB
Product description
36. 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 its value if the degree of dissociation of the weak electrolyte is α.
Determine the pH value of strong and weak electrolyte solutions.
Numerical values of Cm and α: Cm=0.01 mol/l; α=2.7*10-4
Electrolytes: [Cd(NH3)6](OH)2 and HBO2
