Potassium Interdependencies

Actually, the more interesting situation is (b) where the conjugate acid is an oxidizing agent (12). A striking demonstration of the interdependence of electron transfer and oxide transfer is inherent in the following observations. It is possible to prepare a solution of potassium iodide in a very pure nitrate melt and maintain... 

Interdependence ofphosphorus, nitrogen, potassium andmagnesium translocation by the ectomycorrhizal fungus Paxillus involutus. New Phytologist, 149, 327-37. 

In Figure 5(a) a scatter plot of the concentration of sodium vs. the concentration of potassium, from Table 7, is illustrated. It can be clearly seen that the two variates have a high interdependence, compared with magnesium vs. potassium concentration. Figure 5(b). Just as the absolute value of variance is influenced by the units of measurement, so covariance is similarly affected. To estimate the degree of interrelation between variables, free from the effects of measurement units, the correlation coefficient can be employed. The linear correlation coefficient, rjk, between two variables j and k is defined by.
