AI Thread Summary
In the discussion about the oxidation numbers of carbon and nitrogen in the compound (NH4)2C2O4, it is clarified that the oxidation number of nitrogen is -3, not -4, as the oxidation states must sum to the charge of the ammonium ion (NH4+). For carbon, the oxidation number is determined to be +3, not +4, based on the oxidation states of oxygen, which is -2. The conversation highlights the importance of correctly calculating oxidation numbers by considering the overall charge of the ions involved. The initial claim of carbon being +4 is corrected through this analysis.

What is the Oxidation Number of Carbon and Nitrogen In this compound (NH4)2C2O4?? i think the oxidation number of carbon is (+4) and Nitrogen is (-4).
am i true?? or not?
Note:this is not a homework.

I can't judge whether you are true :-)
I only can tell you that you are wrong.

Can you tell me why and where ??
 
So let's take NH4-: H has oxidation number +1 and the oxidation numbers have to sum up to the total charge of the ion, -1. That gives -3 for nitrogen. Same argument with C2O42-: Oxygen has oxidation number -2. Leaves me with +3 for carbon.

@DrDu - confusing typo in your post, it is NH4+ - unless it was premeditated :wink:

Thank you guys. I thought that carbon has a oxidation number of +4 in this compound.
Thank you so much for help.

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
