What does the roman number III indicate in cobalt III oxide indicate?
Wiki User
∙ 15y ago
The roman number III indicates that the ion of cobalt present in this form of cobalt in the cobalt oxide is Co3+. Since cobalt also exists as a Co2+ form, these must be distinguished in some way. The standard is to use roman numerals to denote the charge.
Both Cobalt (III) oxide and Cobalt (II) oxide still have the chemical formula of Co3O4.

What is the rule when writing the name of an ionic compound that contains a transition metal?
To indicate the oxidation number using Roman numerals. e.g. Ferric oxide or ferrous oxide /??? Which Ferric oxide (Fe(II)O). Ferrous oxide (Fe2(III)O3). or Potassium permasnganate KMnO4 The manganese is (+7) . hence KMn(VII)O4
How are oxidation states of transition metals indicated in the names of metal compounds?
Roman numerals are used to indicate oxidation states.
What is co hso4 3?
Cobaltic Bisulfate The formula is poorly constructed. It should probably appear as Co(HSO4)3. "Cobaltic" is somewhat archaic. The Stock system, using Roman numerals, is preferred. Therefore, it would be called cobalt (III) bisulfate or cobalt (III) hydrogen sulfate.
What do Roman numerals after an ion name indicate?
It is only needed after transition metals, so it should say how many valence electrons are in the transition metal. Ex: If iron has 3 valence electrons and it is combined with oxygen, it would be written as Iron (III) oxide. I hope It helped!
What is binary name of Cu2O?
this compound can be called copper I oxide or cuprous oxide. the I roman numeral stands for the +1 ion that the copper makes (two positive two ions each lose an electron, while the oxygen ion demands to gain two). More info at http://en.wikipedia.org/wiki/Copper(I)_oxide
What is the letter u in roman numerals?
roman numerals indicate a number not a letter as such there is no answer to that question
In the name cobalt 11 phosphate what does the roman numeral reveal about cobalt?

What is the point of Roman numerals in science?
Roman numerals are a simple way to distinguish between closely-related objects. Two examples:In chemistry, Roman numerals can indicate the valence number of an element in similar compounds, such as with iron (II) oxide and iron (III) oxide.In astronomy, they can enumerate planets, such as Sol III (Earth) and Sol IV (Mars).
What is 2003 in Roman Numerals?
In Roman Numerals, the number 1,000 is represented by "M", thus, to indicate 2,000 you would double it. 1 is represented by "I". So 2003 would be MMIII in Roman Numerals.
CuO in roman Numerals?
Copper(II)Oxide
How can roman numeral in a chemical name be used to write a chemical formula?
The Roman numeral following the cation tells you the oxidation number of that cation. For example, Cu(ll)chloride tags you it is CuCl2 because the (ll) after Cu indicates an ox. no. of 2+.
What is the roman numerial for the number 5000?
(V) or V but with a line above the numeral to indicate multiplication by a thousand. Numerals in brackets also indicate multiplication by a thousand. (V) = 5*1000 = 5000
What was the main purpose of Roman art?
To indicate wealth and status
What is the name of the compound MnO2?
MnO2 is Manganese (IV) Oxide. It is also known as manganese dioxide, manganese oxide or as the naturally occurring mineral pyrolusite. Please see the related links below.
What does the roman mean in an ionic compound?
A Roman number in the name of an ionic compound gives the absolute value of the oxidation number of that element in the compound which immediately precedes the Roman number. This is most common with cations of elements, such as copper and cobalt, that can form stable cations in more than one oxidation state. Copper(II) chloride, for example as the formula CuCl2 while copper(I) chloride has the formula CuCl.
What Elements have roman numerals?
Iron, Chromium, Cobalt, Copper, Lead, tin, mercury, and nickel.
