The answer lies within the concentrations of nitric oxide and sulfur dioxide in polluted air. I am a chemist, and I'm used to strange looks when I say that. James Watts - Navarre, Florida Grumpy old man 3 checking in. By starting at a low temperature, the particles do not collide with much energy giving a slow reaction. Stone Buildings and Monuments in Acid Rain Marble and limestone have long been preferred materials for constructing durable buildings and monuments. Check out a chemistry book from your library. These crystals can disrupt the crystalline arrangement of the atoms in the stone, causing the fundamental structure of the stone to be disturbed.
Also in this report will be an outline. In some areas of the United States, the pH of rainwater can be 3. In my experiment, I will use an overall volume of 50 cmÂ³ of 2moles of dilute hydrochloric acid and keep that constant throughout the entire experiment. Lola, Look up calcium carbonate on wikipedia, this is a basic reaction and is listed in their examples. If you give us an unbalanced equation, I'll be happy to balance it for you and explain how it's done.
Brian Terry aerospace - Yeovil, Somerset, United Kingdom September 25, 2012 Q. Get rid of most of the inventory at the end of the year. Thus, porosity is an important factor in determining a stone's durability. In calcareous soils, acid can be applied to dissolve soil calcium carbonate. I will use 40cm3 of hydrochloric acid instead of 50cm3.
One strategy for limiting the amount of acid pollution in the atmosphere is scrubbing. · I will use 1g of calcium carbonate. For safety I will wear safety goggles to protect my eyes from the possibility of the acid splashing on my face. You can also change the rate of the reaction by adding a catalyst, which is something that speeds up the reaction. Limits nutrient High Ca concentrations will react to form.
Also you will learn a lot about chemical reactions. Compute the mole fraction i. I predict that the higher concentration of acid, the higher the rate of reaction. Daniel Montanes - Cañuelas, Buenos Aires, Argentina Hi Ted, it is very similar here. One day you too may be a grumpy old chemist! Write a balanced chemical equation for the dissociation of nitric acid in water.
The higher concentration of hydrochloric acid will increase the amount of successful collisions per second as there will be more hydrochloric acid particles to collide with the calcium carbonate particles. Surface area of a solid. When no more carbonate dissolves, the acid has been. We started off with testing 25cm³ of 3-molar hydrochloric acid to 2g of calcium carbonate medium size chips we decided a medium size chips before we started our pre-test as we had a choice of 3, small, medium, large. A discussion started in 2003 but continuing through 2018 -- some of these students probably have their PhDs by now :- 2003 Q. Maybe the school administrator and the science teacher who talk to me about this issue are exaggerating? In 1982, the pH of a fog on the West Coast of the United States was measured at 1. The conclusion I have reached is what I predicted before the experiments had taken place.
I will also wash out the beaker in which I will perform the experiment after each use. · I will set up the clamp stand and gas syringe. We did not choose temperature as our independent variable as sustaining the temperature required was hard to do, and getting chemicals to a certain temperature was very difficult. Prediction: I predict that the heating the hydrochloric acid will effect it as heating is one… 2295 Words 10 Pages Aim It is to tell how the reaction between magnesium and hydrochloric acid will be effected if we change the concentration of hydrochloric acid. · The amount of gas produced by the reaction in a certain amount of time. Your body lives and grows because of chemical reactions, whether by taking medicine or even a breath. It is as simple as that.
Matter interacts to form new substances through a process called a chemical reaction. Gypsum is soluble in water, so it is washed away from areas that receive a heavy flow of rain. To extend my investigation I could do the same experiment at but using a different variable such as changing the concentration or the amount of calcium carbonate. This is probably down to human error, as there was no large difference in temperature that day. The aim of this investigation is to find out how the concentration of hydrochloric acid affects the rate of reaction with calcium carbonate. · I will quickly attach the syringe to the beaker of solution.
