    Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

    Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

    Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through 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

    Abstract This lab is performed in order to determine the total energy in a reaction between zinc and hydrochloric acid. The reaction is done twice‚ once to measure the heat of the reaction and again to determine the work done in the system. This is because Enthalpy equals heat plus work (∆H= ∆E+W). Heat and work can be broken down further into separate components so the equation used in lab is ∆H=mc∆T + PV. Many calculations are used in the lab to find out what cannot be measured directly (ex:

    EXPERIMENT 4 Title: Preparation of magnesium sulphate. Date:11.02.2010 Aim: To prepare magnesium sulphate Theory: Magnesium sulfate (or magnesium sulphate) is a chemical compound containing magnesium‚ sulfur and oxygen‚ with the formula MgSO4. In its hydrated form the pH is 6.0 (5.5 to 6.5). It is often encountered as the heptahydrate‚ MgSO4·7H2O‚ commonly called Epsom salt. Anhydrous magnesium sulfate is used as a drying agent. Since the anhydrous form is hygroscopic (readily absorbs water

    Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques
