What would be the first thing you would do if you got burned by a chemical while performing a lab expeiment

If it is on your clothing as well, remove that article of clothing. Then, go to your instructor and report the situation, However if you are by yourself (which you shouldn't be while performing an experiment), immediately call 911. DO NOT put ice on the burn or try to wash it off because you do not know how the chemical will react with either of them ...

You should notify your instructor so they can know how to solve burn
