What is the correct name for cro3?
chromium compounds
…is chromium oxide, commonly called chromium trioxide or chromic acid, CrO3, in which chromium is in the +6 oxidation state.
How do you make cro3?
Production, structure, and basic reactions
Chromium trioxide is generated by treating sodium chromate or the corresponding sodium dichromate with sulfuric acid:H2SO4 + Na2Cr2O7 → 2 CrO3 + Na2SO4 + H2O. Approximately 100,000 tonnes are produced annually by this or similar routes.
What is the molar mass of CrO3?

What is the Valency of CrO3?
Answer: the valency of Cr in Cr2O3 is +3.
What is the use of anhydrous CrO3?
In the passage given above, it is written that when Chromium trioxide is in anhydrous medium, i.e there is no water present in it, then it is used in the isolation of aldehydes from alcohol.
What is the cation and anion of CrO3?
CrO3 C r O 3 contains one chromium ion and three ions of oxygen. Hence, one cation of Cr6+ C r 6 + and three anions of O2− are present in CrO3 C r O 3 .
Is CrO3 basic?
Assertion: NO is an acidic oxide while CrO_(3) is a basic oxide. <br> Reason: Oxides of metals are generally basic and oxides of non-metals are generally acidic.
Which is called chromic anhydride?
CrO3 is regarded as the anhydride of chromic acid. It is one of the most powerful oxidizers known.
What is the cation and anion in Cr2O3?
Now, an ionic compound must be electrically neutral, which implies that the total positive charge coming from the cation must be balanced by the total negative charge coming from the anion. In this case, you need 2 chromium(III) cations and 3 oxide anions in order to have a neutral compound. 2×[Cr3+]+3×[O2−]→Cr2O3.
Which of the following compounds is chromium III?
Thus, two chromium (III) cations and three oxide anions are required in order to have a neutral compound. Hence, the chemical formula of chromium (III) oxide is Cr2O3 .
What is the oxidation number of chromium in Cr2O3?
