Is it normal to think that piss burns stuff like an acid?

whenever i urinate, there is a slight burning sensation in my urethra that goes with the process. i sometimes think that piss is acidic enough to burn things slowly. like urinating on a brick wall would slowly corrode a hole as large as the residual spot of pee on the wall. like if i was for some reason thrown in jail i could break out by using this tactic. other times i feel like it could be used as biological warfare to burn down crops of entire countries just by crop dusting them with a cartridge of urine, devastating the entire population via food deprivation and/or humiliation because they have just got peed on by their enemy . when i pee on plants and bugs i usually feel remorse for the living thing i have just pissed upon. oh well.
