We have a mixture of 100 mL of Fe3+ solution (1.00 × 10–3 M) and 100 mL of A- ion solution (1.00 × 10–3 M). The mixture has a deep blue color, indicating the formation of a complex between Fe3+ and A- . From spectrophotometric analysis, we find that 30.0% of the Fe3+ is in the form of a complex, where there are two probable formulae: FeX2+ or FeX3. a. Balance the following equations and calculate the concentrations of the remaining species. b. After reaching equilibrium states, write the equilibrium expressions and the equilibrium constants for both cases in (a).
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
