The formula for this reaction is:
Variable Factors The factors that could slow down or speed up this reaction are: The hotter the materials, the faster the reaction and vice-versa. Prediction From previous experiments I have learned that if large pieces are broken into smaller pieces they react faster because they have more surface area.
This is because at the molecular level, there are more molecules at the surface of the chips for the molecules of acid to react with when the chips are broken into smaller pieces. The same principle can be applied to the marble chips.
The smaller the chips the more surface area so I predict that the smaller marble chips will react faster than the larger chips.
Method Here is the set up: In this experiment I will be keeping the variables I mentioned earlier the same except one to keep the experiment fair. I will be changing the size of the marble chips to see which size reacts the fastest.
The gas syringe is firstly clamped to the stand and a plastic tube and bung are attached to the syringe. The marble chips are then measured out I will be using 2g of marble chips each time and the hydrochloric acid 10ml is added to the flask.
The chips are then added and the bung is quickly placed over the flask to create an airtight seal.
The amount of carbon dioxide in the gas syringe is read off every 10 seconds until the reaction stops or the gas syringe runs out of capacity ml.
Risk Assessment Goggles must be worn at all times to prevent acid going in eyes. Gas syringes must be handled with care to prevent accidents Variables Table Dependant Variable Value How Measured Amount of carbon dioxide collected Amount read every 10 seconds.
Size measured by third party. Weighed using digital scales. Control Variables Amount of acid 10ml each time Measuring Cylinder Concentration of acid 1 molar acid Measured by third party.Rates of Reaction: Hydrochloric Acid + Calcium Carbonate Essay Sample Background Information: Hydrochloric acid is a clear, colourless, highly-pungent solution of hydrogen chloride (HCl) in water.
It is a highly corrosive, strong mineral acid with many industrial uses. Calcium carbonate is a chemical compound with the formula CaCO3.
It is a common substance found in rocks in all parts of the world, and is the main component of shells of marine organisms, snails, coal balls, pearls, and eggshells. Get custom essay sample written according to your requirements. urgent 3h delivery guaranteed. Order now.
Planning. I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid.
CaCo3 + 2HCL. Investigating the Rate of Reaction of Calcium Carbonate Chips Essay - Investigating the Rate of Reaction of Calcium Carbonate Chips Introduction: In the reaction between calcium carbonate (marble chips) and hydrochloric acid a reaction occurs and the gas carbon dioxide escapes.
The Effect of the Particle Size on the Rate of Reaction Essay Sample. CaCO3 (s) + 2HCl(aq) –> H2O (l) + CO2 (g) + CaCl(aq) Variables: CaCO3 Chips – Once the HCl is poured into the Flask.

Marble is calcium carbonate and thus behaves in the same way: CaCO3 (s) + 2HCL (aq) CaCL2 (aq) + H2O (l) +CO2 (g) In this experiment, I am going to see if temperature affects the reaction rate between marble chips and hydrochloric acid by timing the release of carbon dioxide in the reaction.
