Single crystals of KTb(C(2)O(4))(SO(4))(H(2)O), potassium aqua-terbium(III) oxalate sulfate, were obtained under hydro-thermal conditions. In the crystal structure, the Tb(III) atom is coordinated by four O atoms from two oxalate anions, three O atoms from three sulfate anions and one O atom from a water mol-ecule within a TbO(8) distorted square antiprismatic coordination. The potassium and te...

Effect of Potassium Sulfate Application on Some Physiological Characteristics Date Palm Plantlet Zahedi Cultivar (Phoenix dactylifera cv. Zahdei) Under Water Stress

In previous papers (1, 2) it has been shown that in dilute aqueous solutions aldehydes may be oxidized in the a! position by oxidizing agents such as ceric sulfate, potassium dichromate, and potassium ferricyanide. Normal butyraldehyde and isobutyraldehyde yielded the most conclusive results; the latt,er was converted by ceric sulfate at 80’ into cr-hydroxyisobutyraldehyde and acetone. The evol...

Tonsillectomy is one of the frequent operations performed by Otolaryngologists world over. Otolaryngologists are in search of a technique of tonsillectomy where the operation time and operative blood loss is less. Objectives: This study was carried out to evaluate the effect of aluminium potassium sulfate (> 99% pure) on tonsillectomy time, blood loss during the surgery as well as on the number...

vineyard management, plant nutrition, irrigation, genotype and pests and diseases are effective factors quantity and quality of crops. among mentioned factors, plant nutrition has more importance and nutrient imbalance in soil can affect crop quantity and quality. grape cluster necrosis at veraison time is important disorders in vineyard, because of lack of balance between potassium and magnesi...

The solubility of K2SO4 in water at 25°C was determined. Comparing the value ofthermodynamic solubility product constant, Ksp(th), (Ksp(th) = exp (-ΔGodiss RT) of the mentionedsalt to the value of concentration solubility product, Ksp(c) which is obtained from the observedsolubility, s/moL-1, Ksp(c) = 4s3, revealed a great difference. The difference can be satisfactorilyexplained using Debye- H...
