Rehabilitation and recovery are also needed with families that are affected by substance abuse. For rural towns‚ the development of a formal substance abuse prevention

crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it does not cause a chemical or flammable reaction to the substance. Then‚ we continue with the process until the solution is ready

demonstrate the properties of mixtures and their ability to be separated by physical means. INTRODUCTION: This lab was based on the separation of the components of a mixture. A mixture can be defined as a physical combination of two or more pure substances. Separation techniques are used to separate components that are not chemically combined. All of these techniques involve changes in the physical state of a chemical compound rather than chemical changes. The three objectives in this lab were

Then‚ some of the unknown will be measured and poured into the flask. Also way the flask and the unknown. Add distilled water and phenol saline to the flask. Set that aside to prepare the biuret.

temperature at which the solid is in equilibrium with its liquid‚ and this characteristic is very unique‚ so a substance can be determined by the melting point. Determination of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and cost-effective technique which remains a strong link to the vast
