In the experiment, it proved that the repetitiveness、 reproducibility、 comparability of the 2.0%(NH_4)_ 2CO_3 was better than the original method through repeated experiments. The result of it was equal to the sum of water soluble sodium and the exchangeable sodium and it had better precision and accuracy. The 2.0%(NH_4)_2CO_3 could be chosen as the probational measurement of total alkality.

在本试验中,通过多批次的重复试验证明,2.0%(NH_4)_2CO_3法的重复性、再现性、可比性良好,测定结果稳定可靠,在数值上等于水溶性钠与交换性钠的总和,而且有较好的精密度和准确度,可以作为测定总碱度的试用方法。
