Pop Rocks and Bleach
« on: March 22, 2005, 12:08:14 AM »

My daughter is doing her 6th grade science project, and has come across a situation that nobody can explain.

The experiment involves disolving pop rocks in various liquids - determining if Ph has an effect on the reaction time.

All was fine until she tried household bleach (Ph 11.0).  The reaction time was significantly faster, and shortly after the pop rocks disolved - the bleach began to boil! :Confuzzled:

We checked the temperature, and the bleach had heated to over 144 degrees F.  

Why???

Pop Rocks are Sugar with compressed CO2 bubbles - when the sugar disolves on your tongue, the gas is released, causing the pop.

The question is:  what caused the reaction?

First off, nice name. Now we all know your age!  :D

Bleach contains sodium hypochlorite (NaOCl) which is quite reactive with organic compounds (it oxidizes them) , including sugar. That's why it's a good antiseptic and cleanser.
