Investigation of Hydrochloric Acid with Indigestion Tablet
Introduction In this coursework I go out be public lecture about the proveations, which I score done over two weeks. This gave antithetical egresss by utilise different concentrations of hydrochloric supermans (HCl) and indigestion substitute tablet. I leave behind likewise mention the time which was taken in the investigate, to see how unwavering the hydrochloric acid alikek with indigestion tablet with different concentrations. indigestion tablets are foundation and they are employ for to ravage the prodigality acid in the stomach. dyspepsia Tablet Indigestion is caused by excess acid in the stomach. The tablets neutralise some of this pungent and this is known as Neutralization since it neutralizes the acid. In this look into the essence of acid neutralised by one tablet is found. This whitethorn be considered a direct quantifyment of the effectiveness of the tablet. Requirements for the experimentIndigestion Tablets Calcium Carbonate (CaCO3)Gas JarClamp Sta ndHydrochloric acidic (HCL) solutions labelled 20, 30, 40, 50 60gdm-3 ( these butt be 0. 0, 0. 75, 1. 00, 1. 25,1. 50 mol dm-3)Trough or containerMeasuring cylinderTimer.Bung obstetrical delivery organ pipeConical Flask 50 cm3Indigestion Tablets An indigestion relief tablets alkali in solution, so that it can easily neutralize the excess hydrochloric acid in the stomach. The indigestion tablets to be used in the experiment was purchased from Super Drug Gas Jar A shove off shake up is a straight and thin cylindrical electron tube with ml units. This is used to pucker gas or generate in the laboratory.In my investigation gas jar entrust be used to collect and measure the amount of carbon dioxide gas released during the investigation. pic picClamp Stand Clamp stand is rattling useful and it ascertains attached to the burette or any flask and it allows it to just s nobble in its position. Otherwise, in that respects a possibility of dispensing to a greater extent amount of liquid than its usual measurements. In my investigation conical flask leave alone be attached to the clamp stand so that it can be connected to the delivery tube which will in turn be connected to the gas jar through the water in the trough.Hydrochloric Acid Solution Our stomach produces hydrochloric acid which kills bacteria which maybe present in our food and withal create acidic conditions for the enzymes to work properly. If the stomach contains too much acid then it can cause pain and it is called INDIGESTION. sometimes the acid escapes from top of the stomach which causes pain in the tube ahead(p) to the mouth this is called heartburn The equation of hydrochloric acid being neutralized by sodium bicarbonate looks like this 2HCl + CaCO3- CaCl2+ H2O+ CO2 Delivery TubeDelivery tube delivers the gas in to collecting vessels or container, more(prenominal)over in this case it is going to go in a burette. Delivery tube also allows the gases to go through it this will make the take to be accurate. Trough Trough is used for seeing up the water, and it holds in the water, as well as the burette where gases put themselves off. The delivery tube gets clamped into the water and connected to the gas jar. It usually looks like a normal flat based bowl. Bung Bung is a big clump of rubber, which act as seal in a conical flask.This allows the gas to be delivered through the delivery tube, and the delivery tube is connected with the gift since it has a hole. It is really useful in the experiment therefore no gas can be released outside. Timer Timer is there to get the provides of the different solutions of hydrochloric acids. It makes the result really convenient as well as precise. Conical Flask This is scientific equipment which is usually seen in the lab. In the experiment it was used for to hold the hydrochloric acid and the indigestion tablet. It gets sealed at the top by a bung.Hypothesis In this experiment I will test the hypothesis that how readily an indigestion tablet reacts does not take care on the concentrations of hydrochloric acid. Method for the experiment There will be using various equipments to test the hypothesis. Firstly, I will measure 50cm3 of hydrochloric acid with worst concentration into a conical flask. Then I will get up the trough or the container up to the ? of it. Thereafter, I will fill the gas jar with water then, I will put my clear on top of the open end, and invert over the water in the trough.Followed by, compress the delivery tube in to the gas jar. I will then put one indigestion tablet into the acid, and then quickly place the bung over the conical flask and start the timer. Finally, I will stop the timer when the gas jar is completely full of gas. Once I get my result I will memorialize the time in a table as well as repeat the same procedure two times to get a consistent result. The whole procedure will repeated for the remaining concentrations of the hydrochloric acid and results will be re corded in a table. Below is the experimental set up for my investigation. Table of results Concentration of Time taken to collect 54cm3 of carbon dioxide gas/sec hydrochloric acid/ mol/dm3 1 2 3 Average time 1. 5 126 141 121 129 1. 5 214 243 240 222 1. 0 237 241 307 239 0. 75 319 318 389 314 0. 50 388 377 376 380 pic Analysis of Results Collision Theory Collusion theory is that response which is caused by the reactant particles in the experiment, the more particles in the concentration then there is more causation of the collision theory. 1. Temperature The rate of the chemic reaction can be raised by change magnitude the temperature. This rate can also be increased by increasing the concentration of a reactant in solution in my experiment I have used the Hydrochloric Acid (HCl) with high concentration and our body temperature.This caused by the reactant particles to move quickly, and have more energy in order to collide often, and more of the collision result took in a reaction. 2. Surface Area The rate of a chemical reaction can also be increased by increasing the surface area of a solid reactant. But in my experiment I have dropped the whole tablet, instead of crushing the tablet. This has affected my experiment a lot because there couldve been more collision, but since I have put the whole tablet inside that caused a small intensiveness of space inside.This didnt allow the reactant particles to perform collision theory. It also do the rate at its average point. 3. Concentration My experiments dissolve reactant increased then they became crowded which again caused the particles to perform collision theory. This core that the hydrochloric acid (HCl) with higher concentration means that there is more particles with energyNo No please state this in a better way The result of the line graph shows that the higher the concentrations, the speedy it will react.The hydrochloric acid with higher concentration means there is more reactant particl es which will have more energy and be crowded. There is a greater of colliding, which will also allow the rate of reaction to increase. As the rate of the hydrochloric increases , the rate of chemical reaction becomes quicker. Please comment on the slope of the graph coating The conclusion shows that the higher the concentration, then the reaction will be quicker as mentioned above. Gas Jar
