Question

Provide the stock notation for the following compounds :HAuCI4, TI2O, FeO, Fe2O3, MnO and CuO.

Answer 1

Answer:

So first of all the oxidation number of each metal in the compound should be known

HAuCl4 → Au = 3    

Tl2O → Tl = 1  

FeO → Fe = 2  

Fe2O3 → Fe = 3    

CuO → Cu = 2  

MnO → Mn = 2

These are the oxidation number of each metallic element    

This cant be represented as stock notation as,    

HAu(III)Cl4, Tl2(I)O, Fe(II)O, Fe2(III)O3, Cu(I)I, Cu(II)O, Mn(II)O, Mn(IV)O2

Explanation:

The stock notation is used to represent the oxidation number of metal by Roman numerals.
