When a substance undergoes a chemical change, the product exhibits different physical properties than the starting material. Des
elena55 [62]

Answer:

I) Change in solubility

II) Change in boiling point

III) Change in colour

Explanation:

A chemical change involves formation of new products and is not reversible.

So, once two liquid solutions are mixed and a chemical change takes place, the new product will have the following:

- a new solubility rate, i.e it will dissolve at a rate different from the two liquid solution

- a new boiling point i.e it takes a new point at which its molecules liberate to yield vapour

- a new colour might be detected, as the individual solution each has its own colour
