Measurements of the activities of bases in soils

, : Measurements of the activities of bases in soils. J. Soil Sci, 6: 137-146

The activities of Al, Ca, K and Na hydroxides were determined in suspensions of soil in chloride solutions of widely differing concentrations by measuring the ratio of activity of the metal chloride to the activity of HC1. For each of the 4 ions used there is a range of dilute chloride solutions within which the hydroxide activity is easily measurable and is nearly independent of the chloride concentration.

Palpating a nominated spinal level is a prerequisite to more complex tasks such as palpating the level most likely to be the source of the patient's symptoms. The aim of this study was to investigate the reliability of physiotherapists with a...
