Superior in that it doesn't get excreted quickly when it's in excess? Not so because it is slow in correcting excess alkalinity, or alkalosis.By your definition, it makes bicarbonate sound superior - if I burp out the excess CO2 quickly, what does it do me?
On burping, I have no idea what it would do. Are you thinking you would burp? I don't recall ever burping as a result of drinking soda personally. If it ever happened, it would be inconsequential as I don't recall being the least bit being affected by it.
