IIUC flux prevents burning on the metal surfaces (solder would not adhere well where there is oxidisation) and aids the solder in spreading out.
Keeps the metal chemically clean and prevents it oxidising. This enables to solder to "wet" the surface of the metal.
rips teh oxides off the metal you want to solder to so it flows and makes a surface (alloy? amalgam?) anyway, its the oxide ripping part that makes it work
It's a form of acid, cleans the copper giving a better seal with the solder
