Question

Element X forms `X^(3+)` ions. What would be the formula of the compound formed when reacts with chlorine?

Answer 1

`XCl_3`.........

Explanation:

Chlorine gas is an oxidant, and typically gives `Cl^(-)` ions.........with an atom, `X`, that forms an `X^(3+)`, we could propose its oxidation reaction as..........

`X+3/2Cl_2(g) rarr XCl_3`

And in fact that there are metal and non-metal elements that could be so oxidized, i.e. to give `PCl_3` or `TiCl_3` or `FeCl_3`......
