溶度积（solubility product）是指在一定温度下，溶液中某种物质溶解的产物浓度的乘积。氢氧化亚铁的化学式为Fe(OH)2，而碳酸亚铁的化学式为FeCO3。比较两者的溶度积大小需要比较它们溶解过程的平衡常数（Ksp）。根据平衡常数表，Fe(OH)2表现出较小的Ksp值，大约为4.87 x 10^-17。而FeCO3的Ksp值约...

(2008): Solubility of Fe-ettringite (Ca6[Fe(OH)6]2(SO4)3*26H2O), Geochimica et Cosmochimica Acta, 72(1), 1-18.G. Moschner, B. Lothenbach, J. Rose, A. Ulrich, R. Figi, R. Kretschmar, Solubility of Fe-ettringite (Ca6[Fe(OH)6]2(SO4) .26H O), Geochim Cosmochim Acta (...
From the thermodynamics and kinetics views, the formation of Fe(OH)3/FeOOH and Ca6(Al(OH)6)2(SO4)3·26H2O (Al-AFt) was favored instead of Ca6(Fe(OH)6)2(SO4)3·26H2O (Fe-AFt) as the solubility product (log(Ksp)) of Fe-AFt was −44.0 higher than that of Al-AFt (−44....
Fe(OH)2(s)= Fe2+(aq)+2OH-(aq) Precipitates Precipitates are the solid products that form in the net ionic reaction. Fe(OH)2(s)= Fe2+(aq)+2OH-(aq)does not result in any precipitates forming. Enter an ionic equation (solubility states are optional) to calculate its complete and ne...
Solubility of andradite, Ca3Fe2Si3O12, in a 10 mol% NaCl solution at 800 °C and 10 kbar: Implications for the metasomatic origin of grandite garnet in cal... The results permit a test of a model of CaSiO3 dissolution in NaCl solutions to three dominant aqueous species: CaCl+, OH,...
Ettringite (Ca6[(Al(OH)6)]2(SO 4)3·26H2O) is a naturally-occurring mineral and an important product of the hydration of Portland cements and fly ash. Substitution of Cr(III) for Al(III) and CrO4 for SO4 in the ettringite structure has b... RB Perkins - The solubility and thermod...
Despite the higher sensitivity of melanoma towards ferroptosis and photodynamic therapy (PDT), the lack of efficient ferroptosis inducers and the poor solubility of photosensitizers restrict their synergistic strategies. With unique advantages, carbon do
The model has been used to determine the solubility of Fe(III) in seawater as a function of pH. The results are in good agreement with the measurements of Byrne and Kester and Kuma et al. When the formation of Fe organic complexes is considered, the solubility of Fe(III) in seawater ...
Low bioavailability of iron due to poor solubility of iron(hydr)oxides limits the growth of microorganisms and plants in soils and aquatic environments. Previous studies described accelerated dissolution of iron(hydr)oxides under continuous illumination, but did not distinguish between photoreductive dissol...
