A method for the direct determination of the potassium-calcium activity ratio in soils with a potassium-selective electrode and a calcium-selective electrode was developed. The two electrodes were inserted into the soil suspension, and the potential

Vermiculite prepared from biotite by interlayer cation exchange was reacted with solutions exhibiting redox potentials between 625 and 765 mV. The redox potential was controlled by the Fe2+/Fe3+ activity ratio, measured with a Pt electrode, and kept

The interactions of potassium and calcium ions with two variable charge soils and one constant charge soil were examined by measuring the pK-0.5pCa value with two ion-selective electrodes, together with measurements of single ion activities. The cons

Octahedral ferrous iron in K-depleted micas can be oxidized by Ag + ions penetrating from AgNO 3 solutions into expanded interlayers by ion exchange. Crystalline metallic silver is produced by this reaction. A blue colour develops as a result of oxid
