Sorry, my apologies.
After adding Na2S2O3, the Varsol layer became colorless and there was no change in the Aqueous layer.
Hello.
I have this question for my class.
We were to mix Na2S2O3 to a a test-tube with Varsol layer on top and an Aqueous layer (of I2/KI) on the bottom. I observed a lighter colour change in both layers. How would I express that as a chemical equation?
Also, I added saturated KI to a test-tube with the same two layers. The pink colour in Varsol got lighter and the colour in Aqueous solution also got lighter. How would I write this as a chemical equation?
Thanks

Also forgot to include:
I2(aq) + I- <-> I3- (aq) = AQUEOUS LAYER
I2(aq) <-> I2 = VARSOL
I2(aq) + I- <-> I3- (aq) = AQUEOUS LAYER
I2(aq) <-> I2 = VARSOL
