Today we did the hydrogen peroxide "lab". We were not able to do the actual lab part of it and got data to calculate instead. We had to calculate the masses of the potassium permanganate and hydrogen peroxide solutions used and used that data to do a stoichiometry problem with molarity. It was a helpful practice with molarity and stoichiometry especially since I have been absent for the past few days. Lastly, we had to calculate a mass percent of the hydrogen peroxide using our data from previous calculations, and we learned about how hydrogen peroxide decomposes in light causing an inaccurate advertised percentage on the bottle.
