Florence is only able to find 0.015 M aqueous KI/I2 on the reagent cart, so they perform a dilution by combining 10 mL of water and 10 mL of the available reagent. They now have 0.0075 M aqueous KI/I2 which can be used at station C. Is there a difference in the chemical composition of the solution Florence made from what was available on the reagent cart? Group of answer choices no, because water was already present in the solution yes, because water was added to the solution
