Salt Error of Indicators Due to Standard Alkaline Buffers Themselves. Ii
Previous results of the comparison of colors given by indicators in alkaline buffers and pure aqueous sodium hydroxide have been repeated and confirmed. The electrometric determinations show that the sodium hydroxide was pure and gave theoretical values for the concentration of hydroxyl ion. The slight but distinct neutralising effect of dilute solutions of alkali has been measured electrometri...
متن کاملThe Salt Error of Indicators Caused by Standard Alkaline Buffers Themselves
1. It is found that with many indicators there is a big discrepancy between the true alkalinities or pH values of solutions of pure sodium hydroxide and of standard alkaline buffers which give the same actual colour. This discrepancy must be ascribed to salt error caused by the buffer itself and exceeds in the most extreme case two whole units of pH; that is, an error of 100 fold in determining...
متن کاملThe Effect of reclamation of salt affected lands to Cropland on soil quality indicators
In this study the effects of land use change from salt affected land to cropland on soil quality indicators were studied in Chahafzal region, Yazd province, central Iran. Composite soil samples from 0-30 and 30-60 cm depths of saline and cultivated land were taken. Soil particle size distribution, calcium carbonate, Available water capacity (AWC), Electrical conductivity (ECe), Soil reaction (p...
متن کاملStandard error as standard?
To the Editor: I am concerned about errors in simple statistical concepts in articles recently published in Circulation. First, I worry about the widespread use of the standard error of mean (SEM) to describe the variability of numerical data. Specifically, SEM was used in 30% of the clinical investigations and reports and in 76% of the basic science reports analyzed for this purpose (the first...
متن کاملA Standard Error: Distinguishing Standard Deviation From Standard Error
A recent Perspective in Nature issued a call for more transparency in the reporting of preclinical research (1). Although this article focused primarily on experimental design, it emphasized the need for improved reporting in the scientific literature. Within the context of preclinical studies, there have been discussions regarding the appropriate reporting of standard error (SE) and standard d...
