  • The Reactions Of Halocoalkane's Reaction With Halogenalkane

    In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

  • Hydrogen Peroxide Reaction Lab Report

    Trend The constant, 0 v/v % hydrogen peroxide solution, did not react with the catalase, therefore it was recorded as 300+ seconds and had a reaction rate of 0 seconds-1. The 0.1 v/v % hydrogen peroxide concentration recorded a reaction rate of 0.17 seconds-1. The 0.2 v/v % hydrogen peroxide concentration, recorded a lower reaction rate than the 0.1 v/v% at 0.14 seconds-1. The 1 v/v % hydrogen peroxide concentration recorded higher at 0.49 seconds-1. The 3 v/v % hydrogen peroxide concentration…

  • The Sowbug Experiment

    Sowbug Experiment Introduction A sowbug is an isopod that belongs to the Classic Crustacea family. They live in damp, wet, dark environments and are commonly nocturnal. They are mostly found under rocks, rotting tree bark, or logs in moist, dark areas outside. Through the observational study I observed that the sowbugs most often moved towards the edges and buried themselves, they moved quickly, and they mostly stayed and/or ended up on the damp-dark soil rather than the dry-light sand. Based…

  • Neutralize Ph Lab

    Purpose: To find the pH of different household items and to see what substances are acids or bases. To see how different substances neutralize each other. Hypothesis: I hypothesize that cleaning products will be bases and foods and substances we ingest will be acids. Materials: • Oil • Finesse Shampoo • Anti Freeze • Drain Opener • Hand Soap • Vinegar • Oxy clean • Pine-Sol • Hydrogen Peroxide • Apple Juice • Ammonia Procedure: 1. All materials were gathered, and safety goggles were put on.…

  • Clean Flame Test Wire

    A clean flame test wire was inserted into 0.2 M NaCl and also placed on the flame reputedly. A bright yellow persistent flame was a positive test of sodium being presented, then repeat the same instructions for the unknown ion. After the flame test wire was clean 0.2M KCl was dipped into the flame resulted a lavender color after several trials as well as the unknown solution. 10 drops of 0.1M Ca(NO3)2 in a test tube and 2-3 drops of 1M Na2C2O4, a white precipitate of calcium was present. The…

  • Le Chatelier's Principles Of The Generic Buffer System

    is controlled by the hypothalamus and pituitary gland by a buffering system. A buffer solution is used to maintain the pH at a safe acidity. “A buffer solution is an aqueous solution consisting of a mixture of a weak acid and its conjugate base or a weak base and its conjugate acid” (Boundless, 2010) Equation 1 – Generic Buffer Equation HA (aq) + H2O (l) --> H3O+(aq) + A-(aq) Note that equation 1 is reversible, and all equations that are reversible have to be at a state of.equilibrium.…

  • Fruit Peels Essay

    RESULTS AND DISCUSSION The discussion will cover the obtained results under the following heads: 1. Effect of some different parameters on the behavior of drying rate Fig.1 showed the relation between drying rate and drying time under two drying methods of fruits peels. It was cleared that the drying rate decreased continuously with drying time. There was not any constant-rate drying period and all the drying operations are seen to occur in the falling rate period. The drying rates were higher…

  • Schiff Base Brigand Essay

    3.7.1. Effect of solvent and pH The influence of the solvent on Schiff base ligand L and its metal(II) complexes were studied. The results showed that the optimal solvent for Schiff base ligand L, Co(II), Ni(II) and Cu(II) complexes were CH3CN at λemi =320, 310, 316 and 330 nm, while the optimal solvent for Mn(II) complex was DMF λemi = 312 nm, as shown in Figure 7. The effect pH on the fluorescence intensity of Schiff base ligand L and its metal(II) complexes were investigated between…
