Iodine clock reaction
« on: January 20, 2020, 01:18:35 PM »
Hey guys.
I had a lab last week in which I had to change the sodium thiosulfate concentration and see how it would affect the rate of reaction. The lab procedure can be found at this address: https://edu.rsc.org/resources/iodine-clock-reaction-demonstration-method/744.article
My problem is my reaction started to produce bubbles and I don't know why.
Can you help me?

Decomposition  of Peroxide creates Oxygen. ( bubbles)
