ELI5: Why does your nose burn when you burp through it after drinking sodas?

drinking soda makes unstable solution of CO2 ( carbonic acid ). after consumption drink releases CO2 and it again gets condensed in respiratory track to form a dilute carbonic acid..

Or this could be due to brisking phosporic acid in it.
