Chemistry Help Please :)
The experimental part is that, say we add 4 ml of water, 2 drops of saturated iodine in KI solution.. etc. to the reaction in the introductory paragraph. We are suppose to predict the colour changes in the two phases when each is added to the initial reaction.
Chemistry Help Please :)
I'm stuck on how to do these 4 problems concerning Chemical Equilibriums. When varsol and iodine/pottasium iodide solutions are mixed, the two phases form.. phase A (top) would be pink and phase B (bottom) would be brown. What are the colours in each phases for these 4 add...
