When do you need to use a roman numeral in the name of a compound?
Typically use use the Roman numeral with a metal after a metal in an ionic compound to indicate which ion is indicated in the compound. The reason for this is that many metals can form more than one kind of ion. For example, copper can form Cu+ ions or Cu2+ ions, and iron can form Fe2+ ions and Fe3+ ions.
Overall redox equation fo MnO4 reacting with Fe2 in acid solution give Mn2 and Fe3?
8H+ + MnO4- + 5Fe2+--> 5Fe3+ + Mn2+ + 4H20
What.........Fe2O3 is named iron (III) oxide because it contains . a. three unpaired electrons c. three iron atoms b. Fe3 plus ions d. O3 plus ions?
b. Fe3 plus ions
Identify the reagent that separates fe3 plus?
To separate Fe3+ ions, one can use a reagent like ammonia (NH3) which forms a complex with Fe3+ ions called iron(III) hydroxide. This complex precipitates out of the solution, allowing for the separation of Fe3+ ions from other components in the mixture.
How can potassium thiocyanate be used to confirm that fe2 plus ions have been oxidized to fe3 plus?
Potassium thiocyanate can be used to confirm the oxidation of Fe2+ ions to Fe3+ ions by forming a blood-red complex with Fe3+, known as iron(III) thiocyanate. Upon the addition of potassium thiocyanate, if a blood-red color formation is observed, it indicates the presence of Fe3+ ions, confirming the oxidation of Fe2+ ions.
What is the individual ions for iron iii and sulfate?
The individual ions for iron (III) are Fe3+ ions. The individual ions for sulfate are SO4^2- ions.
What happens when FeCl3 is dissolved in water?
When FeCl3 is dissolved in water, it dissociates into Fe3 ions and Cl- ions. This forms a solution that is yellow-brown in color due to the presence of the Fe3 ions.
What is fe3 plus plus cl?
FeCl3
Is the solution FeCl3 acidic basic or neutral?
The solution of FeCl3 is acidic. This is because when FeCl3 dissolves in water, it forms Fe3+ ions and Cl- ions. The Fe3+ ions react with water to produce H+ ions, which makes the solution acidic.
What is the name of ionic compound fe2 plus?
The name of the ionic compound Fe2+ is iron(II) or ferrous ion.
Does FeCl3 dissociate in water?
Yes, FeCl3 dissociates in water to form Fe3 ions and Cl- ions.
What is the name of the compound Fe2?
ferrous ions and Fe3+ is ferric ion
What is the name of the ionic compound Fe2?
ferrous ions and Fe3+ is ferric ion
What metal forms 3 ions?
Iron is a metal that can form three ions: Fe2+, Fe3+, Fe4+.
