Rate of Reaction Coursework

We investigated whether reaction rate changes when acid concentration is changed when marble is dissolved in hydrochloric acid. Equipment Marble Fragment Erlenmeyer flask Hydrochloric acid gas syringe duct stopwatch To test fairly the general test test, use the same amount of acid for each concentration. Because they are very accurate, I do this by using capillaries. I use 3 grams of marble at each acid concentration. Before starting the experiment for the next different experiment, clean up everything.

Science course - factors influencing the reaction rate of magnesium and hydrochloric acid. Background knowledge has four factors that affect response speed, all of which are dependent on collision theory. This is basically how difficult it is and how often particles collide with each other. The more collisions, the more difficult it is, the faster the reaction time. When the acid concentration is high, collisions tend to occur because particles increase. - Examination of the influence of different concentrations in the reaction of magnesium and hydrochloric acid The purpose of this study was to determine how the concentration of magnesium (HCL) diluted with hydrochloric acid (HCL) and water (H 2 O) influences the reaction rate It was to investigate. The reaction rate will be measured by the amount of released hydrogen (H 2). It is measured every 10 seconds during the experiment

Experimental studies investigating factors influencing the reaction rate of magnesium belt and hydrochloric acid examined factors influencing the reaction rate of magnesium belt and hydrochloric acid. Chemical reactions between substances are caused by particle collisions. The more collisions, the shorter the response time. - Examination to investigate how acid concentration influences the reaction rate of hydrochloric acid and calcium carbonate (magnesium band) -------- My study seems to influence the reaction of CaCO3 and HCl We aim to find a way to change the concentration of acid to evaluate. To test my experiment fairly, I change only one of the variables. It is the concentration of acid.

In the actual course experiment, we decided to change the factor that affects the response speed. I would like to know how changing the concentration of one of the reactants affects the kinetics and make sure the prediction of my effect concentration is correct. I predict that the higher the concentration of reactants, the faster the reaction time will be. In my course experiment, I decided to investigate how changing the concentration of hydrochloric acid affects the reaction rate. At room temperature, I reacted hydrochloric acid with sodium thiosulfate and the reaction rate was measured using the "crossover" method described above. For each experiment, the acid concentration was lowered from 30 cm 3 to 5 cm 3, and water was diluted to 5 cm 3 with acid. I always keep sodium thiosulfate at 30 cubic centimeters and repeat each reaction twice.
