$2 \, mL$ of Dettol is added to a beaker containing $500 \, mL$ of water and stirred. State four observations that you make.
(N/A) $(i)$ The level of water remains almost the same because the particles of Dettol occupy the spaces between the water particles.
$(ii)$ $A$ colloidal solution is formed,not a true solution,as Dettol particles are dispersed in water.
$(iii)$ The water turns milky white due to the formation of an emulsion.
$(iv)$ The characteristic smell of Dettol can be detected even after repeated dilution,which demonstrates that matter is made up of very small particles.
