balanced chemical equations

[clairehaiba]

hi,

This is my question; identify the postive charged ion present in an aqueous solution of selenius acid. write a balanced equation for the breakdown of selenius acid in water and deduce the charge on the other ion that is formed.

Selenous acid is H2SeO3. What is the ion, derived from this acid?

 

When this acid is broken down, it is converted to selenium (this is a notorious thing, solutions of selenites or selenous acid very easily become red, due to formation of selenium). You need a reductor for this.
