Iodine Clock Experiment (Clock Reactions A-Level IB Chemistry)

Outlining clock reactions and how they can be used to show how the concentration of reactants affects the rate of a reaction. The iodine clock (Harcourt-Esson) experiment using hydrogen peroxide, potassium iodide and sodium thiosulfate is shown, using experimental data to find the order of reaction with respect to iodide ions.

I am grateful for this video, was extremely helpful. Thank you!

[@obama2523]

Nice one bro

[@chemistry.student]

Thank you! Hope it helped :)

[@johnbrima3182]

thank you

[@ZacharyCooper-kt7lc]

what is the order of reaction with respect to hydrogen ions, and why is it usually excluded from the rate law equation?

[@nia-en7hg]

please do standard deviation

[@chemistry.student]

Great idea - i'll add it to the list :)

[@stiefnoten2409]

Make also some titration reaction video's for us

at 2:00 shouldnt the y-axis be the concentration of the reactant?

[@abu-karz]

It's the rate because rate decreases exponentially with time. Concentration fluctuates
