The aim of this investigation is to find out how the concentration of hydrochloric acid affects the rate of reaction with calcium carbonate. A student investigated how the rate of reaction is affected by concentration in the reaction between calcium carbonate and hydrochloric acid. When excess hydrochloric acid reacts with calcium carbonate, carbon dioxide is produced. g. CaCO3 + HCl > CACl2 + CO2 + H2O. The rate of the reaction was measured using the scales and the time was recorded using a stopwatch. There are many variables that affect the rate of this reaction such as the following: See our example GCSE Essay on Surface Area and Rates of Reaction Between Mable Chips and Hydrochloric Acid now. Measuring reaction rates Aim. Stop the time when the magnesium fully reacts and A student investigated the rate of reaction between calcium carbonate (marble chips) and hydrochloric acid. 0 mL of water In this experiment, we will look at the reaction of hydrochloric acid and calcium carbonate to form calcium chloride salt, carbon dioxide, and water. The A student investigated the rate of reaction between calcium carbonate (marble chips) and hydrochloric acid. Share Tweet Send [Deposit Photos] “Golden rain” experiment How to obtain shiny “golden” crystals This is an acid-base experiment with shells and vinegar and will amaze your kids! Looking for a cool ocean experiment for your next ocean or nature lesson? Shells are made of calcium carbonate. To find out how the temperature of acid effects the rate of the reaction between Hydrochloric Acid and Q6. Add 10. Add ten drops of hydrochloric acid to the well containing the marble chip. Place one piece of marble chip and the pipette containing the hydrochloric acid in two of the wells in the mini well-plate. To carry out this investigation we need to consider several factors: 1) What will we change? Marble is a form of Calcium Carbonate and therefore behaves in the same manner. Calcium carbonate reacts with dilute hydrochloric acid: Calcium carbonate + hydrochloric acid → Calcium Carbonate and Hydrochloric Acid. 1 Hydrochloric acid reacts with solid calcium carbonate in the form of marble chips. This substance is a crucial pillar of human life – it is used in construction, to manufacture paper and plastic, and in many other spheres. of hydrochloric acid into a conical flask 2. Experiment 1 25 cm 3 of 0. This is because it is the only gas in the reaction. The graph becomes less steep as the rate of reaction decreases, due to the reactants being used up. As seen above, there are two ways to measure a rate of • The reaction rate of calcium carbonate and hydrochloric acid, specifically the amount of gas produced. Plan an experiment to determine the percentage by mass of calcium carbonate in the mixture. 4 (aq) + CO. 1. Calcium carbonate and hydrochloric acid. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. The reaction between calcium carbonate and hydrochloric acid produces calcium chloride, water and carbon dioxide. The equation for the reaction is: CaCO 3 (s) + 2 HCl(aq) CaCl 2 (aq) + H 2 O(l) + CO 2 (g) (a) The student plotted results for the hydrochloric acid at 20 Here is a set of typical results for this experiment; Rate of reaction between magnesium and acid results table. Marble is a pure form of calcium carbonate.
