A student has spilled some acid onto their arm. One lab partner suggests pouring some base on it to neutralize the acid but the TA quickly interjects that would be a bad idea and has the student begin washing their arm off in the sink. Provide two different reasons why theneutralization suggestion was a bad idea.
