When varsol and iodine in potassium iodide aqueous solution is mixed, two phases form.

What are the colours in each of the 2 phases when 2ml of I2/KI aqueous solution plus 2 ml of varsol are mixed in a test tube?

What are the colours in each of the 2 phases when each of the following are also added to the test tube containing 2 ml of I2/KI and 2 ml varsol and why:

a) 4 ml varsol

b) 4 ml water

c) 2 drops saturated iodine in KI solution

d) 2 drops saturated sodium thiosulphate

e) 2 drops saturated sodium potassium iodide solution

    all i know is that the varsol phase is pink and the I2/KI phase is brown at equilibrium.

    Thanks for helping :)
    I understand that part, but I don't get in what direction each of the conditions listed above would the equilibrium shift to and how the colour would change.
