Question Title

* 1. You’re working in a laboratory and the lab supervisor has decided that you are going to clean the sodium hypochlorite (bleach) reagent bottles with sulfochromic acid. When you asked the supervisor about the main ingredients of the sulfochromic acid, she replied that it’s strong sulphuric acid with a bit of potassium chromate and that it’s really good at removing unwanted minerals from glassware.

What do you think of the supervisor's idea? Identify what they should do.

Wear a respiratory so he doesn't smell the chlorine fumes when the acid reacts with the bleach.

Rinse the hypochlorite bottles really well before using the acid in them. Bleach and acid are incompatible and chlorine gas could be released if the bottles aren't rinsed.

Wear latex or nitrile gloves, safety glasses, a lab coat before beginning the work.

Work in a fume hood so he does not smell the chlorine fumes when the acid reacts with the bleach.

Discard the hypochlorite bottles in the hazardous waste room since the incompatibility of bleach and acid does not pose a serious risk.
