Question:

‣ A bottle contains either salt or chalk. How will you find out what it has without testing

Answer:

‣ The substance in the bottle can be differentiated by adding water to the bottle, which will mix with the substance present in the bottle

‣ If the bottle contains salt , it will dissolve fully into the water and make a clear solution.

‣ If the content in the bottle is chalk it will form a colloid solution with the water and thus will look like a cloudy mixture of water and chalk particles

‣ So, both chalk and salt can be differentiated by checking the solution of the substance formed with water.
