Question

What is the best reason for a student to remove a dangling bracelet when heating test tubes of acid solutions in a hot water bath in a chemistry lab

Answer 1

A dangling bracelet may dip in the hot water bath and conduct heat to the student’s hand. Sudden sensation of heat could make the student pull his or her hand, upsetting the test tube. If acid inside test tube mixes with water, it may cause a reaction leading to burns and skin irritations.  

There are chances of loose bracelets getting entangled in laboratory equipment, which can have disastrous consequences.
