Hydrochloric Acid and Calcium Carbonate

hcl and caco3

Ok this is the net ionic equation for this reaction:. For this method we needed the following equipment: Empty plastic tub Gas burette Flask Clamp stand Measuring cylinder Stop watch And the equipment was laid out like this: This is a step by step guide to our method: We half filled the plastic tub with water We filled the measuring cylinder full of water and put our thumbs over the top so that no air bubbles could get in. Most people put food in their mouth, chew a few times and swallow their food, as if their sole focus was how quickly they could get their foods to their stomachs. I could also repeat the experiment using different catalysts. Balance the equation for the reaction between zinc and hydrochloric acid. Flask placed on scales with cotton wool blocking up top.

A list of common and occasionally encountered carbonate minerals is given in Table 1 with their chemical composition and their relative reaction with cold and warm hydrochloric acid. I want to find out how different strengths of acid affect the speed of the rate of reaction. Justification For the same mass of the calcium carbonate, powder has a larger surface area than marble chips. The reaction is not, strictly speaking, neutralisation since neutralisation reactions make a salt and water as the only products, and this reaction makes carbon dioxide as well although the acid is neutralised! If you place one drop of cold hydrochloric acid on calcite, the entire drop of acid will erupt with bubbles and a vigorous fizz will last for a few seconds. To do this, you need to be familiar with the properties of various compounds or you need to be told what the phases are for the chemicals in the reaction. The re­duc­ers in the re­ac­tion process are met­al atoms, and the ox­i­diz­ers are hy­dro­gen cations.

What is the balanced equation for the reaction of calcium carbonate and hydrochloric acid

hcl and caco3

The only portion of the mixture that reacts with the hydrochloric acid solution is the calcium carbonate. I will look at the various factors affecting the reaction and select one variable to change, while the others keep constant in order to carry out a detailed investigation. The measuring cylinder supplied for the measurement of Hydrochloric Acid was 100 cm , whereas I only had measure 50 cm so this may have caused an error. Dolomite will effervesce weakly with cold hydrochloric acid, producing a few bubbles. In my experiment, I will use an overall volume of 50 cm³ of 2moles of dilute hydrochloric acid and keep that constant throughout the entire experiment. You then weigh the resulting solution and find that it has a mass of 78. Hydrochloric acid on limestone: This video demonstrates what happens when one drop of dilute 10% hydrochloric acid is placed on a piece of limestone.

The bubbling release of carbon dioxide gas can be so weak that you need a to observe single bubbles slowly growing in the drop of hydrochloric acid - or so vigorous that a flash of effervescence is produced. The form of calcium carbonate. Chem­i­cal re­ac­tions with met­als are main­ly ac­com­pa­nied by the re­lease of hy­dro­gen, and the in­ten­si­ty de­pends on the ac­tiv­i­ty of the met­al, for ex­am­ple the al­ka­line met­al lithi­um re­acts vi­o­lent­ly, while with alu­minum the re­ac­tion takes place weak­ly be­cause of the durable ox­ide film of this el­e­ment. Whilst the ranges did not overlap, showing a real difference in the assorted solutions, I would have preferred to have had smaller ranges, meaning more accurate results. The active ingredients are calcium carbonate 550 mg and magnesium hydroxide 110 mg. Reactants and products are separated by putting an arrow between them to show the direction of the reaction.

If Tums is added to 20. Reaction rate is a way of measuring how fast the reaction takes place. This is what I did: 52. The vapor pressure of water at 24. Vinegar is easy to obtain, inexpensive, and safer to use than hydrochloric acid. Correct this by putting a coefficient of 2 in front of water: SnO 2 + H 2 → Sn + 2 H 2 O This puts the hydrogen atoms out of balance.

This is an ex­change re­ac­tion, the prod­ucts of which are: a weak and un­sta­ble com­pound, car­bon­ic acid which breaks down into car­bon diox­ide and wa­ter. All of these tests damage the specimen and make it less fit for the next group of students. This is because the surface area has been increased, making more dolomite available to the acid. Products are listed on the righthand side of the equation. Many rocks contain small amounts of calcite or other carbonate minerals. In this instance, we are timing how long it takes for our reaction to produce 50cm3 of carbon dioxide. It is a col­or­less liq­uid, al­though in­dus­tri­al acid can have a yel­low tint, for ex­am­ple from a mix­ture of iron.

Also when pouring the Hydrochloric Acid into the beaker some may have been left in the bottom of the measuring cylinder meaning the results may have been inaccurate. The concentration of the hydrochloric acid. Writing acetic acid in the second form shown makes it easier to see what salt will be formed after the neutralization. Oriskany sandstone is often cemented by calcite. The results we obtained we fairly consistent, with all of the results having a range of no more than 10cm3 Carbon Dioxide except the results for the 50% Carbon Dioxide, 50% Water solution. So when con­duct­ing chem­i­cal ex­per­i­ments, it is ad­vis­able to use a res­pi­ra­tor and pro­tec­tive glass­es. The sample reacted completely to produce 1.

Checking if the ranges overlap is commonly regarded as the best method to see if there is a real difference in the results. This reaction was produced in organic elemental analysis to identify C and H. The aim of this investigation is to find out how the concentration of hydrochloric acid affects the rate of reaction with calcium carbonate. When we were handling the hydrochloric acid we made sure that we were extremely careful, and if we did spill and of the solution onto our hands, we made sure to wash it off very quickly, as hydrochloric acid is extremely corrosive. I think he was taking it because his stomach was always unsettled and he took it every day. Evaluation: I think that the method I used got me accurate and reliable results as you can see by the fact that they matched my prediction and I did not really have any anomalous results I think my results were accurate because I carried out my experiment with care repeating the experiment twice and measuring out my substances carefully and accurately.
