【摘要】 本文依据鲍林电负性标度 ,从成酸元素的电负性 ,共价半径和氧化态这三种参数出发 ,推出一个与实验值比较吻合的简便经验公式 :pKa =345x/r +31 .98(lnm ) 1 .9- 1 8.0 0 ,该公式值得推广更多还原

【Abstract】 Taking L.Pauling eleclronegativity as scale,this article proceeds from three parameters-the eleetrone gativity of aeidic a simple,expeniential formmula which tallys wsth the resultes ualue of the experiment:pKa=345x/r+31.98(ln) 1.9 -18.0,personally,the author considers this formula popularizeworthy.更多还原
