The balanced equation will be calculated along with the solubility states, complete ionic equation, net ionic equation, spectator ions and precipitates. 元素中的第一个字符使用大写字母,第二个字符使用小写字母。例子:Fe, Au, Co, Br, C, O, N, F。 替换不可改变的组以避免歧义。例如,C6H5C2H5 +...
All the ions are spectator ions so there is no reaction. Reaction Expressions Enter an ionic equation (solubility states are optional) to calculate its complete and net ionic equations. 12345 67890 +()→ 平衡方程式
Numerous light rare earth elements(LREE)minerals containing Fe and P were processed by sulfuric acid roasting method,and the leaching solution mainly comprises LREE sulfate,Fe2(SO4)3,H3PO4,and H2SO4,however,the solubility data of LREE sulfates in this system is few.This work studies the...
The title compound, diiron(III) trisulfate-sulfuric acid-water (1/1/28), has been prepared at temperatures between 235 and 239 K from acid solutions of Fe2(SO4)3. Studies of the compound at 100 and 200 K are reported. The analysis reveals the structural features of an alum, (H5O2)Fe...
