Answer to Question #93905 in General Chemistry for Kylie

Question

Consider the reaction of sodium hypochlorite with iodine.

Explain why hydrochloric acid can be added using a measuring cylinder and not necessarily a pipette.

Answer 1

As you know, for the reaction of sodium hypochlorite with iodine, a strongly acidic environment is needed. It is the reaction conditions that indicate to us that the use of a graduated cylinder is perfectly acceptable. So, in this situation, the measurement accuracy does not require clear accuracy for a specific pH value, and, as a result, the use of more accurate measuring equipment.
