前言Na2HPO4·12H2O是酸式盐,其水溶液呈碱性。衡量碱性大小的标准是其水溶液的pH值。pH值的大小随其浓度的变化而变化。我们可以通过数学手段推导出pH值与浓度之间的关系,
Preface Na2HPO4.12H2O is an acid salt, its aqueous solution is alkaline. The standard for measuring alkaline size is the pH of its aqueous solution. The pH value varies with its concentration. We can deduce the relationship between pH and concentration through mathematical means,
