1. write out the ion formulas for the components of iron (ii) ammonium sulfate and show the overall formula and how the charges are balanced. 2. write out the formulas for the ions and water components of potassium trisoxalatoiron (iii) trihydrate and show overall formula has the charges balanced.
6. a. What is the percent by mass of water in iron(II) sulfate heptahydrate, FeSO4•7H2O (or what percent of the molar mass of FeSO4•7H2O is due to the waters of crystallization)? b. What mass due to waters of crystallization is present in a 3.38-g sample of FeSO4•7H2O?
- Solving applied mass percent problems Iron(II) sulfate forms several hydrates with the general formula FeSO, XH,O, where x is an integer. If the hydrate is heated, the water can be driven off, leaving pure FeSO, behind. Suppose a sample of a certain hydrate is heated until all the water is removed, and it's found that the mass of the sample decreases by 42.%. Which hydrate is it? That is what is?
1. When iron(II) ammonium sulfate is dissolved in water, it dissociates into its component ions. () → () + ( ) + ( ) 2. When oxalic acid is added, the iron (II) ions precipitate as iron(II) oxalate dihydrate. Fe2+ (aq) + (aq) + __H20 (1) ► ( ) + _ H(aq) 3. Next, potassium oxalate is added to the washed precipitate. Potassium oxalate dissociates into its ions in solution. At high oxalate concentrations, iron (II) oxalate combines with another...
