Hcl Lab Report

The purpose: To investigate the rate of the reaction between Magnesium and different concentrations of HCL.
Hypothesis:
If the concentration of HCL increases, the rate of the reaction between HCL and Magnesium decreases.
Scientific Explanation:
In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have sufficient energy, this can be …show more content…

“Concentration is measured in moles (M) per cubic decimeter; it shows us how man particles there acre dissolved in a substance. Therefore, 1M of hydrochloric acid dissolved in one cubic decimeter of water is the same concentration as 1M of sodium chloride dissolved in one cubic decimeter of water. If the amount of moles per cubic decimeter doubles from 1M to 2M, then so does the concentration double? “ So as the concentration of HCL increases, the rate of the reaction decreases because of the amount of energy that is included in the reaction(it increases as the HCL concentration …show more content…

The difference between the rates of the reaction’s when 1 mole was inserted, and when the 3 mole was inserted is 118.49 seconds. This is the data the proves that my hypothesis is correct, this is because as the amount of mole increase, the amount of energry included in the reaction is more. for example, take the 1 mole of HCL, the 2 mole of HCL, and the 3 moles of HCL. The 1st mole of HCL has more particles than the 2nd mole of HCL, and thus when the 1st mole reacts with HCL, the rate of the reaction will be more because there will be more less energy in the reaction of HCL and Mg, compared to the 2nd mole of HCL and it reaction with Mg, (the 2 moles of HCL has more energy than the 1 mole), so hence, there will be more energy in the reaction . Both mole of HCL(the 2 moles of HCL and the 1 mole of HCL) have less energy , and thus when the 3 moles of HCL reacts with Mg, there is even more energy between the Mg and the HCL particles, so hence the rate of the reaction will be faster.

What could have been done is more trials to make sure

    ABSTRACT To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. In this experiment we examined how increasing the volume of the extract added to the reaction would affect the rate of the reaction. The enzyme used was horseradish peroxidase which helps catalyze hydrogen peroxide. Using different pH levels, the absorbance rate of the reaction was measured to see at which condition the enzyme worked best. The rates of absorption were calculated using a spectrophotometer in 20 second intervals up to 120 seconds.

    Exploration Title: Effect of Temperature on rate of Osmosis Submitted By: Abdulkarim Kamal Date Submitted: October 19th 2015 Subject: Biology HL Teacher: Mr. Nick   Aim: This is an investigation to determine the relation between temperature of a solution (sucrose) and the rate of osmosis Scientific Context: Osmosis is defined a passive transport process in which a fluid diffuses across a semi-permeable membrane, from an area of high solute concentration to an area of low solute concentration and vice-versa. There are various factors that could potentially influence the rate of osmosis; these factors include volume, concentration, and temperature. If all external factors that may interfere with rate of osmosis are controlled, the results will show equal amounts of fluid on both sides of the barrier (membrane); this is known as an “isotonic” state.

  • The Biological Temperature Of Catalase

    Reactions in the human body produce hydrogen peroxide as a product (1). Since hydrogen peroxide is poisonous to the human body, catalase catalyzes hydrogen peroxide into water and oxygen (2 H2O2 → 2 H2O + O2) (1). According to the collision theory, a reaction can only occur if particles collide with sufficient energy to overcome the activation energy and with correct geometrical orientation (3). Increasing temperature increases the kinetic energy of the particles which means that an increase in temperature will increase the speed of the hydrogen peroxide and the catalase molecules which

  • Empirical Formula Of Copper Chloride Lab Report

    729 Words  | 3 Pages

    As soon as the wire was submerged into the solution, the aluminum atoms and the copper (II) ions underwent a reduction-oxidation (redox) reaction, meaning aluminum was oxidized and donated its electrons to the copper ions, which were reduced. As a result, solid copper began to form on the surface of the aluminum wire, giving the wire a brown-orange color that resembled rust. The wire had to be regularly shaken in order to remove the solid copper particles and thereby expose more of the aluminum wire to react with the surrounding solution. As the reaction progressed, the liquid copper chloride solution slowly began to lose its color and turn clear. This was a chemical reaction, as seen by the bubbles formed with the wire was added, meaning gas was released when aluminum was oxidized and copper was reduced, but it also gave rise to physical changes, such as the change in color of the solution from blue-green to rusty orange to clear.

  • Stoichiometry And Limiting Reagents Lab Report

    If only one reactant is increased, then the chemical reaction will only produce a certain amount of products after the limiting reagent is used up, and in this experiment, the most mass the reaction could produce was 0.4 grams. Although we kept adding calcium chloride, not adding sodium hydroxide in the same proportions will not yield more product, which is the main goal in conducting this lab. We should have seen a plateau at 0.4 grams to show that the limiting reagent inhibited further Ca(OH)2 production, but we made several mistakes in our experiment, which made the data unusable to conclude. Once again, the data is polluted, so these number are not accurate, but it is the data our group has to work with. The theoretical yield should have been more than the actual yield, and the percentages should have been less than 100.

    This indicates that the reaction has limited the amount of moles it reacts with. The number of moles in 0.3 grams of baking powder is 0,00357mole. In vinegar it is 0,8375 moles. This indicating that as 0,00357 is smaller than 0,8357, 0,00357 is the maximum amount of moles that can interact with the moles from vinegar. Therefore, once 0,00357moles have reacted of the 0.3 grams of baking powder, the reaction will stop.

    Biochemical tests are the tests used for the identification of bacterial species based on the differences in the biochemical activities of different bacteria. Bacterial physiology differs from one species to the other. These differences in carbohydrate metabolism, protein metabolism, fat metabolism, production of certain enzymes and ability to utilize a particular compound help them to be identified by the biochemical tests. Gram’s stain was originally devised by histologist Hans Christian Gram in 1884. Gram-positive bacteria stain purple, while Gram-negative bacteria stain pink when subjected to Gram staining.
