问答题
A freshly prepared aqueous solution of Pd(NH3)2Cl2 does not conduct electricity. Is this compound to be regarded as a strong or weak electrolyte? Explain in terms of its structure.
【正确答案】Since it does not conduct,it is a weak electrolyte,and the structure involves covalent bonding only. Since there are no ions involved in this compound,the chlorine atoms, eovalently bonded, must be in the coordination sphere.
