it changes the color of cornstarch *improvement* No, its a physical reaction.
This mixing is not a chemical reaction.

No.
Well, there is no chemical reaction, really, since the cornstarch still remains cornstarch. (and if you dry it, it becomes cornstarch again) It's just that the cornstarch lightly bonds to the water which then lightly bonds to other cornstarch, creating a net-like substance. This net is easily broken and made, thus increasing the viscosity of the fluid and adding some other interesting properties to it as well.
Dissolving is a physical process.
