HCl + CaCO3
Rates of Reaction: Hydrochloric Acid + Calcium Carbonate
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. Hydrochloric acid is found naturally in gastric acid. 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. When these two reactants are combined results in the production of Calcium Chloride (CaC2), Carbon Dioxide (Co2) and Water (H2O).
Aim: To investigate the rate of reaction between Calcium Carbonate (CaCo3) and hydrochloric acid (HCl) by changing the molarity of the acid and measuring how much Carbon Dioxide (Co2) is produced.
Hypothesis: I predict that the higher the molar concentration of the acid the faster the reaction will take place therefor creating more gas in a shorter amount of time. I think this will happen because when the acidity is higher the solution is stronger which then speeds up the reaction process.
Safety: For safety I will wear safety goggles to protect my eyes from the possibility of the acid splashing on my face. I will also wear a protective lab coat to stop the acid splashing and burning my clothes and skin.
Apparatus:
· Conical Flask
· Measuring cylinders (15ml, 25 ml, 50ml, 100ml)
· 45 ml of hydrochloric acid (0.5 m, 1 m, 1.5 m, 2 m, 2.5 m)
· 5.4g of calcium carbonate (chip)
- Stand
- Clamp
-Boss head
· Timer.
· Bung. (rubber stopper)
-Electronic scales
-Tea Strainer
Method:
· I will measure out 10 ml of Hydrochloric Acid and pour this into a small beaker. (First 0.1 molar) repeat 3 times for each concentration.
· I will set up the clamp, stand and measuring cylinder.
· I will weigh 0.3 grams of Calcium
