| + | #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. |
