When do you need to use a roman numeral in the name of a compound?
Roman numerals are typically used in compound names to indicate the oxidation state of an element. This is necessary when the element can have multiple oxidation states and is written as a cation in the compound. For example, iron can exist in the +2 or +3 oxidation state, so the compound name "iron(II) chloride" specifies that it is the +2 oxidation state of iron.
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 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.
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+.
What species is reduced in the reaction Fe plus AgNO3 Fe(NO3)3 plus Ag?
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.
What is the ionic equation for nitric acid and iron?
The ionic equation for the reaction between nitric acid (HNO3) and iron (Fe) is: 3H+ + Fe -> Fe3+ + 3/2H2 This equation represents the dissociation of nitric acid into H+ ions and the oxidation of iron to Fe3+ ions.
