2022年7月1日 · The reproducibility data of two analysts performing K 2 O analysis on flame photometer at different times was calculated by the application of T-test which showed that the T-calculated (0.690) is less than T-tabulated (2.262). Thus, the results were non-significant to each other, and method can furnish reproducible results.

Potassium oxide (K 2 O) is an ionic compound of potassium and oxygen. It is a base. This pale yellow solid is the simplest oxide of potassium. It is a highly reactive compound that is rarely encountered. Some industrial materials, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to K 2 O.
