Question

What happens when tellurium(II) chloride reacts with water?

Answer 1

Tellurium(II) chloride is hydrolyzed by water.

Explanation:

Tellurium(II) chloride,

TeCl

2

, will be hydrolyzed by water to form tellurium metal, tellourous acid,

H

2

TeO

3

, and hydrochloric acid,

HCl

.

The balanced chemical equation for this reaction looks like this

2TeCl2(s]+3H2O(l]→Te(s]+H2TeO3(aq]+4HCl(aq]

An interesting thing to notice here is that tellurium, which exists in its +2

oxidation state in tellurium(II) chloride, will be reduced to tellurium metal and oxidized to its +4

oxidation state in tellorous acid.

This implies that you're dealing with a disproportionation reaction, which is the name given to a chemical reaction in which the same chemical species undergoes both oxidation and reduction.

I think that the same reaction pattern can be expected for tellurium(II) bromide,

TeBr2

. The hydrolysis of this compound would produce hydrobromic acid,

HBr

, instead of hydrochloric acid

2TeBr2(s]+3H2O(l]→Te(s]+H2TeO3(aq]+4HBr(aq]

Hope this helps ☺️☺️☺️

Answer 2

it becomes co which is carbon monoxide
