CHEMISTRY COURSEWORK RATE OF REACTION HYDROCHLORIC ACID AND MAGNESIUM

Reactants with high surface area provide a greater binding surface for other reacting molecules, and therefore increase the number of successful collisions at any moment. Even after disappearance of magnesium ribbon, gas bubbles were evident, implying the reaction was incomplete. Add up the weights of the five 10 cm-long magnesium ribbons and obtain the average weight in grams Use the average weight as obtained in 15 above and weigh of an equivalent weight of Magnesium powder for this case 0. Eye protection Each group of students will need: Conical flask cm 3 Single-holed rubber bung and delivery tube to fit conical flask Note 1 Trough or plastic washing-up bowl Note 2 Measuring cylinders cm 3 , 2 Clamp stand, boss and clamp Stopwatch Graph paper. For the 10 cm magnesium metal used, there was slight variation in weight. Prediction Given that, powdered Magnesium metal has a high surface area than equivalent lengths of Magnesium ribbon, we predict that the former will have shorter duration of reaction with hydrochloric acid than the latter.

During the reaction, the water bath in the gas delivery system showed gas bubbles ascending to the gas cylinder. Lesson organisation This is intended as a class practical. Immediately cork the flask to the prepared gas delivery system. Discard all the chemicals, wash, and rinse the conical flasks ready for another procedure. Page last updated October

The concentration of hydrochloric acid used and the surface area of magnezium Magnesium metal used. Retrieved March 8,from newton. Repeat step 5 and 6 for 2M, 1. Syringes should not be allowed to become wet, or the plungers will stick inside the barrels. Introduction In acid-base chemical reactions, there are four main variables, which influence the rate of reaction.

A reaction between Hydrochloric Acid and Magnesium ribbon.

For stance, magnesium metal reacts with hydrochloric to form magnesium chloride salt while displacing hydrogen from the acid as hydrogen gas. The volume of hydrogen gas produced is measured over a few minutes, and the results are used to plot a graph.

This will be changed by using Magnesium ribbons and powdered Magnesium metal in separate experiments. Our new website is coming soon. Powdered solids produces rapid reactions than the same solids in single lumps. Though low hazard, eye protection chemostry necessary as you may get a spray as tiny bubbles burst.

Courseaork eye protection throughout. A table of results showing HCl-Magnesium powder reaction duration seconds in reducing concentration. Data Evaluation The experimentation procedures followed were standard for all the two sets of experiments conducted, including data collection mode. Add up the weights of the five 10 cm-long magnesium ribbons and obtain the average weight in grams Use the average weight as obtained in 15 above chekistry weigh of an equivalent weight of Magnesium powder for this case 0.

Rate of Reaction of Magnesium and Hydrochloric Acid

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. Cut 5 equal sizes 10 cm pieces of Magnesium from the fleshly cleaned Magnesium ribbon, weigh each of them using a digital weighing balance and record their weights. In Search of Solutions: Catalysis of a reaction between sodium thiosulfate and iron III nitrate coursewrk.

From the experimentation the aims of the experimentation have been achieved. The rate of reaction of magnesium with hydrochloric acid.

I’ve worked as rexction volunteer in many different international social projects and as a camp counselor every summer. Each activity contains comprehensive information for teachers and technicians, including full technical notes and step-by-step procedures.

Lesson organisation This is intended as a class practical. Retrieved March 8,from chemguide. Ensure that all naked flames are extinguished, and that there are no other sources of ignition available to students. Determination of end of reaction was sometimes uncertain. The rate of reaction of magnesium with hydrochloric acid Class practical Magnesium reacts with dilute cokrsework acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water.

First, repair your working bench by simply removing unnecessary materials. The duration of reactions were recorded as shown in tables 2 and 3 below. Reactants with high surface area provide a greater binding surface for other reacting molecules, and therefore increase the number of successful collisions at any moment.
