Record the reaction time in a table like Table 1 (below). It is quite reactive giving vigorous reactions towards acids. The volume of the hydrogen gas produced will be measured at room temperature and pressure. These are the sources and citations used to research Magnesium and Hydrochloric Acid Experiment. Clark (2002) explains that, finely divided chemical solids have greater surface area than chemical solids in lumps. Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. Research questions: The balanced formula for this is: Mg(s) + 2HCL(aq) MgCl2(aq) + H2(g) Magnesium + hydrochloric acid Magnesium Chloride + Hydrogen Magnesium will react with The following chemicals and reagents were required in the experimentation: Apparatus and personal protection equipment. This experiment determines the stoichiometry of a reaction of magnesium and HCl by measuring the pressure of the hydrogen gas produced using a PASCO Absolute Pressure Sensor and a PASCO Science Workshop 500 computer interface. 5 7980 • In two experiments, two equal masses of magnesium ribbon were allowed to react with two 50 cm3portions of dilute hydrochloric acid. In further investigation to keep this variable controlled would be to have the temperature of the HCl tested with a thermometer before the acid is combined with the magnesium. Therefore, we sought to test the duration of reaction of equal lengths Magnesium ribbons with reducing concentrations of hydrochloric acid. Experiment 5 Reaction of Magnesium with Hydrochloric Acid OUTCOMES After completing this experiment, the student should be able to: develop a procedure for generating and measuring a gas in a reaction. Add 40 ml of distilled water and label the conical flask with the concentration of the HCL poured. This will reduce reaction errors related to impurities. A The aim of this experiment is to verify the effects of surface area of solid reactants and concentration of aqueous reactants on the rates of acid-base chemical reactions. The main substances that were used in the experiment were hydrochloric acid (HCL) and magnesium ribbon(Mg) when these materials combined there was a chemical reaction, the reaction was that there was bubbling and fizzing when the magnesium dissolved, there was a pattern when the temperatures changed, the molecules in the acid would change speed cause the reaction to be either fast or slow, … The volume of the hydrogen gas produced will be measured at room temperature and pressure. In the experiment the magnesium reacts with the hydrochloric acid to create magnesium chloride and hydrogen. Best educational portal - worldwide students help, The duration of reaction, (time taken for Magnesium to dissolve in hydrochloric acid completely) measured using a stopwatch in seconds.The rate of gas bubbles. Record the reaction time in a table like Table 1 (below). Measure 40 ml of 3M HCl using a clean dry measuring cylinder and pour into a clean 100 ml conical flask. A constant amount of excess HCl is reacted with varying amounts of magnesium solid. The ratio of the cumulative reaction duration above gives 104.8 sec/58.8 sec = 1.78. magnesium (Mg) is known as a chemical element with the atomic number of 12.
