Is milk SMELLING sour a physical or chemical property? I know that milk souring is a chemical change, but the question does mention the senses. Please help.
It's not chemical because it would have to react to something to change so it is physical change because it is the same thing but it just smells I hope this helped
No I actually took this last year. When milk turns sour it's a chemical change. You can't undo a chemical change as for a physical change it's reversible. Trust me on this one.
