#Open PhET simulation called salt and solubility.
#Click on the tap to fill the water up to 5 liters.
#Select the salt NaCl from the menu and click on the salt bottle to add the salt into the vessel containing water by shaking the bottle.
#Now click on the tap present at the bottom of the vessel to remove water . click and shake the salt bottle to add little more salt.
#Again click and shake the salt bottle to add more and more salt, now observe the solubility.
#Click on the tap to add 5l of water in to the same vessel.
#Click on the slightly soluble salt and select mercury bromide.
#Click on salt bottle to increase or decrease the concentration of mercury bromide into the vessel by shaking the bottle.
#Click on design a salt menu and adjust cation and anion charge.
#Click on salt bottle and shake to add designed salt to the vessel.
#Click on the tap to remove or to fill the water into the vessel.
==Developmental Questions (What discussion questions)==
==Developmental Questions (What discussion questions)==
#What changes you observe when salt is added to the vessel?
#what you observe when remove water and more salt into the vessel?
#when you add water to the same vessel what happens to the solubility the table salt?
#what happens to the solubility when mercury bromide is added to the vessel containing water?
#What do you observe when you increase or decrease the concentration of mercury bromide and water?
#What are the changes you observed when you added your own designed different types of salts?
