Thermodynamics of the solubility of potassium nitrate in the mixed solvent, Ethanol+Water, and the related Ion-association
Using the evaporating method, the solubility of potassium Nitrate was determined in various mixtures containing Water and Ethanol at 25°C. The results show that the solubility of KNo3 decreases with increasing the mass percent of Ethanol in the mixtures. This trend is along with decreasing the dielectric constant of Water+Ethanol mixtures. Moreover, it can be concluded that the totqal solubilit...
متن کاملKinetic spectrophotometric determination of trace amounts of nitrite ion using potassium bromate-murexide mixture in acidic media
A new, simple, rapid, and cheap method for determination of trace amounts of nitrite ion is reported.Determination is based on reduction of bromate ion by nitrite ion, in the presence of murexide inacidic media. During reaction of bromate ion with nitrite ion, the reaction mixture is decolorized.The absorbance changes is then monitored spectrophotometricaly at 520 nm, at 25 °C. Dynamicrange of ...
متن کاملIncreasing salt tolerance in Olive, Olea europaea L. plants by supplemental potassium nutrition involves changes in ion accumulation and anatomical attributes
The effects of supplemental potassium were studied on growth, ion concentration and anatomical parameters in one year old olive trees, Olea europaea L., grown in sand culture in greenhouse at different levels of NaCl for 80 days. The experiments were conducted in a completely randomized design as a factorial. Factor one was salinity (0, 40 or 80 mM NaCl) and the second factor was potassium leve...
متن کاملThermodynamic Study on the Interaction between Fe2+(aq) ion and LAlanine
Using UV-VIS spectrophotometric method, the formation constant for interaction of Fe2+(aq) ion with L-Alaninewas experimentally studied at pH = 4.1 ± 0.01 (50mM of potassium hydrogen phthalate buffer), ionic strengthof 0.1M potassium nitrate and at 5 different temperatures 15,20, 25,30 and 35 T. The optical absorption spectraof mixtures containing considered cation and L-Alanine were analyzed b...
متن کاملGrowth response and ion distribution of two canola varieties to different potassium to sodium ratios
Rapeseed (Brassica napus L.) is a crop relatively tolerant to salt. The effect of different ratios of NaCl/KCl was studied in two cultivars (Hyola308 and Kristina) of Rapeseed in 2002. Canola seedlings were grown in Hoagland’s solutions, which were salinized by different ratios of NaCl/KCl. The treatments or KCl:NaCl ratios were 0:0 (control);10:10; 20:0 (Total Added Salt or TAS=20 mol.m-3), 0:...
متن کاملWater relations, pigment stabilization, photosynthetic abilities and growth improvement in salt stressed rice plants treated with exogenous potassium nitrate application
Potassium is a major nutrient which may play an important role in many processes such as ion homeostasis in plant cells and osmotic adjustment of guard cells during stomatal opening and closing. Pathumthani 1 (PT1) rice has been reported as being a salt sensitive cultivar and has been selected as a model plant in this study to investigate the possibility of improving the osmotic potential, pigm...
