Magnesium and hydrochloric acid experiment write up
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a shiny gray solid which bears a close physical resemblance to the other five elements in the second column (group 2, or alkaline earth metals) of the periodic table: all group 2 elements have the same electron configuration in the outer electron shell and a similar crystal structure.
Hydrochloric acid is a strong acid that is commonly used in labs for a variety of purposes, including the digestion of proteins and the testing of pH. It is a clear, colorless liquid with a pungent, corrosive smell.
In this experiment, we will be reacting magnesium with hydrochloric acid to produce hydrogen gas and magnesium chloride. The balanced chemical equation for this reaction is:
Mg + 2HCl -> MgCl2 + H2
To set up the experiment, we will need the following materials:
- Magnesium ribbon or powder
- Hydrochloric acid
- Beaker or test tube
- Heat source (such as a bunsen burner)
- Gas collecting tube or balloon
To begin the experiment, we will first measure out a small amount of magnesium and place it in the beaker or test tube. Next, we will carefully add hydrochloric acid to the beaker or test tube, being sure to avoid spilling or splashing the acid.
Once the acid has been added, we will place the beaker or test tube on the heat source and observe the reaction. As the magnesium reacts with the hydrochloric acid, it will produce hydrogen gas, which will be visible as bubbles rising to the surface of the solution.
At the same time, the reaction will also produce magnesium chloride, a white solid that will form in the bottom of the beaker or test tube.
To collect the hydrogen gas produced during the reaction, we can attach a gas collecting tube or balloon to the top of the beaker or test tube. As the hydrogen gas is produced, it will be collected in the tube or balloon.
Once the reaction is complete and all of the magnesium has been consumed, we can turn off the heat source and carefully remove the gas collecting tube or balloon. We can then observe the collected hydrogen gas and measure its volume, if desired.
Overall, this experiment is a simple and easy way to demonstrate the reactivity of magnesium and the production of hydrogen gas. It also provides an opportunity to observe the properties of the products produced during the reaction, including the appearance and physical properties of magnesium chloride.

The following transactions occurred in October: a. Experiment 1 In the first experiment, half a gram of magnesium was combined with 3 milliliters of hydrochloric acid in a glass beaker. Zinc will arrive in each to gas, and t here would balance this equation. The mass of the NaHCO3 had changed after the reaction occurred along with after it was placed on the hot plate and being in the drying oven. .
The rate of reaction of magnesium with hydrochloric acid
You have the right balance, the equation for the cows, the nation of the team now before NGO. Replace the magnesium with an equal mass of aluminum? A slurry was created by adding 50 ml of hexane to the beaker containing the silica gel. Okay, so therefore the lumber move off saying, because to 10 my sake divide by them on the massive scene. Then the mass of copper sulfide was subtracted by the copper to get the mass of sulfur. Hcl hydrochloric acid, yeah, sweet magnesium hydroxide, right? Now we have to balance this equation. The reaction between magnesium and hydrochloric acid combine to form a salt of magnesium chloride and release hydrogen gas.
Similarities Between Magnesium And Hydrochlorimetry Lab Report
Using forceps, place the magnesium ribbon into the Petri dish. For the Magnesium ribbon, the lengths of the Magnesium ribbon used will be constant, while quantities of powdered Magnesium metal in grams will be equivalent to the weight of the length of magnesium ribbon used. So sword of my museum. Therefore, this study intends to investigate the effect of concentration and surface area of reactants on the rate of chemical reactions. Therefore, we sought to test the duration of reaction of equal lengths Magnesium ribbons with reducing concentrations of hydrochloric acid. Use 365 days for calculation 9.
Investigation into the Reaction Between Magnesium and Hydrochloric Acid Free Essay Example
Also, there could be description or a standard time of how much oxygen should react with magnesium so that the exact mass of magnesium oxide could be Sandwich Blitz Unit 6 Lab Report 301 Words 2 Pages Conclusion: Compare Trial 1 and Trial 2. Chemical properties are simply the set of chemical changes that are possible for that substance. So let's say we are mg three, which is followed. Ensure that there are no naked flames. In addition, impurities may form on the surface of the magnesium metal therefore, slowing further the rate of reaction.
What happens when you mix hydrochloric acid with magnesium?
There were two masses taken for the substance NaHCO3- one with the evaporating dish and one without, subtracted out after the lab was concluded. At higher acid concentration, the rates of bubble forming were rapid than those in lower acid concentrations were. These occurrences very possibly caused a slower than expected reaction between the metal and acid. The concentration of 2HCL you use is the independent variable because it will vary, and the time taken for the rate of reaction to take place i. All the reaction will be carried out under a constant temperature room temperature of 25 0C. To calculate the percentage of Zn, we divided the final mass of the penny 2. The materials were massed once before and once after being heated in the drying oven.
Magnesium and Hydrochloric Acid
Oh, who would you not call it? After the experiment the mass had slightly decreased. This will reduce reaction errors related to impurities. Illustration of a reaction that produces a gas. This complies with my prediction. This brought a slight confusion in stopwatch reading.
A reaction between Hydrochloric Acid and Magnesium ribbon.
Then, 25mL of 0. Half fill the trough or bowl with water. Similarly, the duration of reaction will be determined using equivalent weights of powdered Magnesium metal. The mass staying the same shows that mass was not added or destroyed. Temperature influences the rates of reaction through kinetic energy, such that high temperatures increase the kinetic energy of reacting molecules therefore causing frequent collisions, which form products faster. This demonstration may also be performed using a document projector if a dark background is used.
Magnesium(s) hydrochloric acid(aq) magnesium chlorideâ€¦
Illustration of an oxidation-reduction reaction. Magnesium will react with hydrochloric acid. So number more just would be total because to sue upon 5171 gram T or by two grams per mole. Students should not have access to any source of ignition. Or twice produces mg cl two plus two H two.
