2 ml of dettol is added to a beaker containing 500 mL of water and stirred. State four observations that you can make.

When 2 ml of dettol is added to a beaker containing water, one can see that:


(a) Dettol completely mixes with water. After mixing, one cannot distinguish the dettol content from water.


(b) The smell of dettol could be identified after stirring.


(c) A slight colour change can also be observed while stirring. The mixture becomes slightly white in colour.


(d) The concentration of dettol is reduced. The effects (for example the ability to kill germs) shown by the mixture of dettol+water is less than that of 2 ml of dettol alone.
