Rate of Reaction Between Calcium Carbonate and Hydrochloric Acid Plan: In my experiment I will measure the rate of reaction between calcium carbonate and hydrochloric acid. The rate of the reaction is the speed that the reaction takes place so by measuring the rate I will measure the amount of time the reaction takes. Hydrochloric acid is a strong acid that is found in digestive juices in the stomach, it is also used for cleaning metals before they are coated. Calcium carbonate has a few forms including chalk and limestone the main use of these two materials is in the making of concrete, which is used for many things such as buildings. When you put calcium carbonate and hydrochloric acid together they react to form calcium chloride, carbon dioxide and water. Hydrochloric acid + calcium carbonate arrow calcium chloride + carbon dioxide + water. HCl(aq) + CaCO3(s) arrow CaCl2(aq) + CO2(g) + H2O(l) Things that affect the reaction rate of this experiment are: 1. The temperature of the hydrochloric acid. 2. The amount of hydrochloric acid. 3. The concentration of the hydrochloric acid. 4. The surface area of the calcium carbonate. 5. The amount of calcium carbonate. 6. The form of calcium carbonate. (It is available in three forms powder, small stones or large stones) 7. You can speed up the reaction by stirring the solution. 8. You can also change the rate of the reaction by adding a catalyst, which is something that speeds up the reaction. In my experiment I will change the temperature of the hydrochloric acid. I will not change anything else; I will keep the amount of calcium carbonate, the form of calcium carbonate, the concentration of hydrochloric acid, the surface area of the calcium carbonate and the amount of hydrochloric acid all the same. I will not add a catalyst to my solution and I will not stir my solution. · I will use 25cm3 of hydrochloric acid. · I will use 1g of calcium carbonate.
the acid was at 14 C the magnesium took 141 seconds to react and 27 C
Investigating the Rate of Reaction Between Marble Chips and Hydrochloric Acid I am investigating the rate of reaction between marble chips (calcium
activation energy needed to be activated. I have chosen to do concentration of acid because surface area is difficult to measure, pressure is hard to do in a school lab, and temperature could be dangerous e.g. if acid boils it could spit.
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.
Reaction 1: CaCO3(s) + 2HCl(aq) CaCl2(aq) + CO2(g) + H2O(l). GRAPH 14 in both cases represents the mean of the data. Using the equation for enthalpy change: H = mcT. Where: m = Mass of liquid to which heat is transferred to (g). c =
The aim is to find out if changing the concentration of the hydrochloric acid solution has an effect on the time taken for the reaction. The reaction that will take place is: Hydrochloric acid + Calcium Carbonate + Calcium Chloride + Water + Carbon dioxide 2HCl (aq) + CaCo3 (s) CaCL2 (aq) + H2O + CO2 (g). Collision theory - Collisions between reactant particles are needed. for the reaction to take place in order to form a product.
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
from 10cm to 50cm to make it easier to see the difference in a graph.
The Effect of Concentration of Hydrochloric Acid on the Rate of Reaction with Magnesium Aim: To investigate the effect of concentration of hydrochloric acid on the rate of reaction with magnesium Prediction: As the concentration of the hydrochloric acid increases, so will the rate of reaction Hypothesis: In a reaction, particles of two different reactants react together to form a product. The reaction only takes place on account of two things, if the particles collide, and if the collision has enough 'activation energy'. The two reactant particles, in this case magnesium particles and hydrochloric acid particles, must collide with each other on the correct 'collision course'. If this does not occur then no chemical reaction will take place. The reaction must also have enough energy, this can be affected by temperature, the more heat the particles have the faster they move and so the more energy therefore more chance of successful collisions.
Controlled variables: Using the same quantity of magnesium and the same concentration of hydrochloric acid. Aim and Purpose The aim and purpose of this experiment is to investigate if the temperature of HCL will affect the rate of reaction between HCL and magnesium. Research Question How does the temperature of hydrochloric acid affect the rate of reaction it has with magnesium? Hypothesis As the temperature of the hydrochloric acid increases, so will the rate of the reaction.
The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
It will be when there is too much HCl for the marble chips to dissolve
An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid
I predict that the following reaction will occur: [IMAGE]CaCO3(s) + 2HCl(aq) CaCl2(aq) + H2O + CO2(g) I also predict that after a certain amount time all the reactants will run out and only the product will be left, only then will the reaction end. Variables A variable is anything which affects the results of an experiment, for example, the variable could affect the speed the particles move or the amount of energy needed in a reaction. For this experiment, there are many variables we could use.
Rate of Reaction - Sodium Thiosulphate and Hydrochloric Acid. Aim Investigation, to find out how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration. Introduction I must produce a piece of coursework investigating the rate of reaction, and the effect different changes have on them. The rate of reaction is the rate of loss of a reactant, or the rate of development of a product during a chemical reaction. It is measured by dividing 1 by the time taken for the reaction to take place.
