等浓度碳酸氢钠和醋酸钠2种溶液的pH大小比较

Comparison of pH Size of Sodium Bicarbonate Solution and Sodium Acetate Solution Under Same Concentration

利用Excel对相同浓度的NaHCO3溶液、CH3COONa溶液中离子浓度的精确计算，得出相同浓度的2溶液中，水解程度一定是HCOa〉CH3COO^-，但不能仅通过水解程度大小来得出pH（NaHCO3溶液）〉pH（CHsCOONa溶液）的结论，2溶液的pH大小还与溶液浓度有关。

This paper used Excel to calculate the concentration of ions in sodium bicarbonate solution and sodium acetate solution under the same concentration, and showed that the degree of hydrolysis of bicarbonate was greater than that of acetate, and the pH size of these two solution depended on both the hydrolysis degree and the solution concentration.
