  • Above Time Vs Temperature Essay

    The above Time Vs. Temperature graph displays the results of an experiment measuring the time taken for a sodium thiosulphate solution, at a certain temperature, to react with Hydrochloric acid. The descending curve in the above graphs suggests that the higher the temperature of the sodium thiosulfate solution the faster the reaction, causing the cluster of data later on in the graph. This is due to the high temperatures causing the increase in the particles average kinetic energy, the more energy provided by the heat of the water baths the faster the particle within the solution are able to move. As a result of the increased movement the particles are more likely to collide in the correct orientation and cause a faster reaction to occur. As the temperature reaches room temperature, moving from right to left of the graph, the reaction time…

  • Essay On Sodium Thiosulphate

    Research Question How does the change in hydrochloric acid concentration affect the rate of reaction between sodium thiosulfate (Na2S2O3(aq)) and hydrochloric acid (HCL(aq))? Background to the Research question Collision Theory Back in 1916, scientists William Lewis and Max Trautz proposed the collision theory, which qualitatively explains how chemical reactions take place and why reaction rates change for various reactions. Chemical reactions involve collisions amongst reactant particles or…

  • Lab Report: Redox Chemical Reactions

    soup” green when it was fully reacted with the two reactants. Part III started with reaction eleven that created bubbles, smoke, and it was fizzing while turning completely white when it reacted. The solid, when dissolved, also created an evolution of foaming gas. The physical observations of reaction twelve where it started to bubbled like a soda, started to fizz and the solution was clear. Then, in reaction thirteen, it turned into a white and foamy substance that kind of looked like milk and…

  • Calorimetric Determination Of Enthalpy Of Sodium Sulfate

    The Calorimetric Determination of Enthalpy and Entropy Changes of the Thermal Decomposition of Sodium Sulphate Decahydrate Abstract Sodium sulphate decahydrate thermally decomposes to anhydrous sodium sulphate at 50⁰ C and cools to form anhydrous sodium sulphate. Using Hess's Law the enthalpy and entropy changes of this process can be determined in order to deduce the spontaneity of the reaction. The transition temperature was determined by melting the hydrated crystals at 50⁰ C and allowing…

  • Ammonium Perchlorate Lab Report

    allowed both size and composition analysis. The system for the introduction of particles was made in a way to produce particles with the same charge. The skimmers were used to separate particles based on their velocity. The system was very complex because each of the parts worked at different pressure. In order to determine the velocity of particles, they were irradiated by two lasers on their way, and the velocity was calculated from the known distance and determined time. The size of particles…

  • 1what Is An Acid-Base Titration?

    The mixture in 2 was titrated against sodium thiosulfate placed in a 50.00 mL burette. 4. Steps 1-4 was repeated untill a difference of 0.01 mL is noticed in values taken. 2.0 LITERATURE REVIEW Experiment 1: Titration is a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of an identified analyte. IN our case, it is an acid-base titration. In the titration the titrant(solution with a known concentration of reagent) is added to the…

  • Creatinine Clearance Experiment

    that demonstrated how renal system responses and reacts when subjects consuming different types of fluids. Respective fluid volumes are based on each subject’s body mass. Based on each subject’s body mass, after converted from pounds to kilograms, every subjects has different volume and fluids for ingestion. For the control subject, she ingested no fluid throughout entire lab which represented the conditions of normal fluid. For the hypotonic subjects, she ingested 854mL of water within 10…

  • Calcification Lab

    “With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2 …

    liquid form. This is a physical change because its actual material that it consisted didn’t change, meaning, it’s still sugar, but in liquid form. Mixing solid copper sulphate with water is a physical change because a new substance was never formed and the copper sulphate is still copper sulphate, but in a different state. Plus the fact that the final product turned into a mixture (solution), which is another sign of a physical change. The changes I examined that were chemical in my experiment…
