【摘要】 就无机化学教学中无机含氧酸的相对酸强度等问题,确立了一种含氧酸及其阴离子的相对酸强度的判据,在不知道Ka的情况下用这种判据来判断酸根离子的水解反应,水合Brφnsted-Lowry酸碱反应以及某些难溶盐在强酸中的溶解性等等,都获得了比较满意的结果。更多还原

【Abstract】 The paper establishes a criterion for the relative acidic strength of inorganic oxyacid and its anion.The criterion is used to infer hydrolysis of acid radical ions;the interaction of hydration Brφnsted-Lowry acids and bases and the solubilities of some slight soluble salt in strong acids and so on under the condition that we don’t know Ka.The results are satisfide.更多还原
