To properly disinfect an item, it would need to be saturated or immersed in a disinfectant solution for at least 10 minutes. But, 15-20 minutes would be better. If you are trying to sterilize the item, you would need to leave it soaking for at least half an hour.

If you cool too quickly, a saturated solution at a higher temperature can 'crash' out of solution.

A chemical change is when the molecules of an object / solution are changed. A physical change is when the object / solution is altered without molecular change. Breaking glass is a physical change.

It is not true that an object will swell in an isotonic solution because there is no different concentration gradient between the object and the isotonic solution
What point is a solution to y>3x-2
Because - allowing the residue of disinfectant to air-dry - leaves the active ingredients on the surface longer. Wiping it dry with a cloth defeats the object of keeping the surface bacteria-free.

A true solution is homogeneous, that is the same all the way through, and you can't see the solute particles nor filter them out. A false solution is properly called a suspension or colloidal suspension. They are heterogeneous and you may or may not be able to see the solid pieces. Colloidal suspensions scatter light.
