Refractive index of two fluids when mixed

[Nikky1988]

Hi all!

I was wondering what will happen if you have two aqueous solutions with the same refractive index and you mix them? Would you end up with the same refractive index as the both solutions or will the refractive index change?

In my case I'm using a aqueous 40% wt. potassium thiocyanate and a sucrose solution of 46.5 % wt.

Hope some of you can help me, thanks!

I don't think there is a simple, universal, answer:
