A physical change is any change that results in the rearrangement of molecules‚ but doesn’t affect their internal structures. When you make rock candy‚ you are creating a physical change. When sugar and water mix together‚ they are not forming a new substance‚ sugar dissolves‚ but it doesn’t disappear. So when you crystallize it‚ it still has the same chemical structure‚ the only thing that changed is the physical appearance. When we create the rock candy it will take about a week or more for it

Paper Chromatography Chromatography comes from the Greek word khromatos (color) and graphein (to write); i.e. paper chromatography is literally color writing on paper. This method tests the purity of compounds and identifies substances. This analytical process‚ despite having been replaced by the success of thin layer chromatography‚ still stands as a valuable teaching tool‚ and is nevertheless very common. This method is very useful because not only is it a relatively quick process‚ but also

DEVELOPMENT Technical The same process for the generic line was used to create the Tamarind Candy except where the ingredients were added. The automation remained the same and that was all the adjustment needed to actually make the product. During this process the terms and procedures are defined and standardized to ensure quality and specification are met consistently.

How Chromatography Helps The Human Race Chromatography is the separation of a mixture by passing it in solution or suspension or as a vapor (as in gas chromatography) through a medium in which the components move at different rates. “Chromatography is done by making of a mixture move past the solids‚ or across the surface of a solid‚ like paper. The mixture is poured onto a solid surface. As the different components of the liquid run down the solid‚ some of them move more slowly than other. A component

Analysis of Food Colorings by Paper Chromatography Introduction Paper Chromatography one method for testing the purity of compounds and identifying substances. This is a useful technique because it is relatively quick and requires small quantities of material. Separations in paper chromatography involve the same principles as those in thin layer chromatography. The substances are distributed between a stationary phase and a mobile phase. The stationary phase is usually
