Physical+and+Chemical+Properties

They finished the physical and chemical properties activity well. We decided to use hand held electronic pH meters. However, they have to be calibrated first.

The activity also includes a separation of mixture section. Due to time constraints we cannot do this hands on. We explained what was invovled in separating mixtures using solubility, filtration and evaporations through examples. We assigned an excercise in separating a mixture of four components. They had to turn in a concept map (flow/chart) of the the separation procedure. The deadline was one week.
