I am having some trouble with writing ternary compounds with oxyacids and acid salts in them.
First how do I determine the charge of an oxyacid? (are they all zero???)
When oxyacids lose oxygen atoms does that affect its charge? if so how can I find out it's new charge.

Also can someone please check if I had answer 3 questions correctly?

1. Hydrogen hypochlorite --->  HClO
2. Copper (II) hypobromite ---> how do u determine the charge of hypobromite?
3. What is the charge of carbonic acid?  ---> zero? but then how would it form bonds?
4. What is the charge of chromic acid ---> zero?

thanks

1. yes
2. Hint: Br and Cl are in the same group
3. yes

Does this mean that all oxyacids have a 0 charge therefore all of them do not form bond with other atoms? but then wouldn't the change in the number the oxygen atoms change their charge?

Also for 2. Is it Cu(BrO)₂

[Yggdrasil]

All of the oxyacids can have the same charge because the oxidation state of the non-oxygen component is different in all of the different species.  For example, consider the following oxyacids:

Hypochlorous acid HClO - oxidation number of Cl is +1
Chlorous acid - HClO₂ - oxidation number of Cl is +3
Chloric acid - HClO₃ - oxidation number of Cl is +5
Perchloric acid - HClO₄ - oxidation number of Cl is +7

Also, 2 is now correct.

I suggest you look at some structures for the more complex oxoacids.

chromic acid as compared to carbonic aid

[Mikez]

thanks!

I never knew that chlorine had so many oxidation numbers, how do I find out the number of oxidation numbers for an atom (when it's not listed on my periodic table for a test)?

Also why would an oxyacid bond with other atoms if it already has a overall charge of 0?
