universal example of dissolving involves a solid and a liquid‚ usually water. When a solid called a solute is mixed with a liquid called a solvent‚ the solute particles breakdown and spread them selves out to be closer to the solvent particles. This mixture is then called a solution. If the solute is coloured it will be easy to see a visible change‚ however if the solute was colourless‚ then the solution may look like the original solvent. The occurrence of dissolving can be seen in many every day activates

Experiment #1: Separation of Acid‚ Base‚ and Neutral Compounds from a Solid Mixture by Liquid-Liquid Extraction Introduction Liquid-liquid extraction is a technique used to separate chemical substances in order to purify or identify the various components of a mixture. Flavors‚ spices‚ perfumes‚ and medicines are just some of the everyday things that are extracted from plants and other natural sources [1]. The basic principle used to carry out this separation is the mixing of two liquids that are

Samuel Beckett described his Waiting for Godot as a tragicomedy. To what extent is this is an accurate description? Would you say there is more tragedy than comedy or a mixture of both? Through the use of many linguistic‚ structural and comic features‚ Samuel Beckett’s Waiting For Godot successfully places a wayfaring line between the two genres of tragedy and comedy. With the opening showing the two main characters Vladimir (Didi) and Estragon (Gogo) in a barren setting with useless props such as

The three separate liquid mixtures each had different ranges of boiling points of the liquids in the mixture. The percent efficiencies of the three separate mixtures were compared to determine which provided the most separation of liquids. Each mixture was heated in a flask and the vapor would begin to rise as the liquid would boil‚ then flow to the condenser and drop to the bottom
