Saturation of solutes
Today students of class 7A participated interestingly in an activity to compare the saturation levels of different solutes available in the kitchen. Different samples of solutes like salt, sugar, coffee etc were made to dissolve in equal quantities of water. Students were excited to know the saturation levels of solutes.
Reactivity of metals with oxygen
Students were taken to the lab to demonstrate the reaction of magnesium ribbon with oxygen. Magnesium burns in air to form a white ash and burns with a luminous flame. When this white powder ash is dissolved in water and tested with a drop of phenopthalpheno indicator, the solution turns dark pink showing that the solution is basic in nature.
