my laptop sucks, otherwise I would have answered to this question.
Use Avogadro's number. 2 mole Fe(3+) ( 6.022 X 10^23/1 mole Fe(3+) ) = 1.20 X 10^24 ions of Fe(3+)
Iron (Fe)
Yes
combination
CuSO4 (aq) + Fe (s) -> FeSO4 (aq) + Cu (s)
Fe 2+ is Ferrous Fe 3+ is Ferric
Iron itself does not conduct electricity when dissolved, as it typically forms ions in solution. However, when iron is dissolved in an acidic solution, it can produce iron ions (e.g., Fe²⁺ or Fe³⁺) that can conduct electricity due to the movement of these charged particles. The overall conductivity depends on the concentration of the ions and the presence of other ions in the solution.
In a neutral compound, the ratio of Fe³⁺ ions to O²⁻ ions is 2:3. This is because Fe³⁺ has a +3 charge, while O²⁻ has a -2 charge. To balance the charges, two Fe³⁺ ions contribute a total charge of +6, which is balanced by three O²⁻ ions contributing a total charge of -6. Thus, the formula of the neutral compound would be Fe₂O₃.
Yes, iron chloride solution is a conductor of electricity. When iron chloride (FeCl3) is dissolved in water, it dissociates into iron ions (Fe³⁺) and chloride ions (Cl⁻), which are charged particles that can move freely in the solution. This movement of ions allows the solution to conduct electric current.
O does not exist by itself. The balanced equation would be 4Fe + 3O2 --> 2Fe2O3

FeSO4, or iron(II) sulfate, can exhibit acidic properties in solution primarily due to the hydrolysis of Fe²⁺ ions. When dissolved in water, Fe²⁺ can react with water to form Fe(OH)⁺ and release H⁺ ions, which contribute to acidity. Additionally, the sulfate ion (SO4²⁻) does not significantly affect the pH, allowing the acidic behavior to be attributed mainly to the iron ions. Thus, the overall result is a weakly acidic solution.
The pH of a solution of Fe(ClO4)2 (iron(II) perchlorate) depends on its concentration and the hydrolysis of the iron(II) ions. Iron(II) ions can undergo hydrolysis to form a weakly acidic solution, which can lower the pH. Typically, solutions of Fe(ClO4)2 will have a pH below 7, indicating acidity, but the exact pH would need to be determined experimentally based on the concentration of the solution.
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
H3PO4 is added to Mohr's salt (ammonium iron(II) sulfate) to prevent oxidation of Fe²⁺ ions to Fe³⁺ ions during permanganate titrations. This reaction interferes with the accurate determination of oxidizable substances and is minimized by the presence of H3PO4, which stabilizes Fe²⁺ ions.
Cr and Fe have four unpaired electrons in their 2 plus ions.
When freshly precipitated Fe(OH)3 is shaken with a dilute solution of FeCl3, the hydroxide can dissolve back into the solution due to the formation of soluble complexes. This occurs because FeCl3 can provide additional iron ions (Fe³⁺), which can interact with the hydroxide ions (OH⁻) from Fe(OH)3, leading to the dissolution of the precipitate and the formation of soluble iron species. The process can also lead to the formation of a colloidal suspension if the conditions favor it.
