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 Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
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 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
The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
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.
Investigating Factors Which Affect The Reaction Between Chalk and An Acid. Introduction: Chalk is just one of the many forms that calcium carbonate can take. It is made of the mineral remains of sea creatures from millions of years. ago.
It will be when there is too much HCl for the marble chips to dissolve
The reason I believe this is that chemical reactions occur when particles of the reacting substances collide. Increasing the number of the particles increases the number of collisions per second and this increases the reaction rate. In the reaction between hydrochloric acid and calcium carbonate you can increase the number of particles in two ways. The first of these is to increase the surface area of the calcium carbonate.
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.
from 10cm to 50cm to make it easier to see the difference in a graph.
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 =
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.
Investigating the Effects of Temperature on the Rate of Reaction between Magnesium and Hydrochloric Acid Introduction Chemical kinetics is the study and examination of chemical reactions regarding re-arrangement of atoms, reaction rates, effect of various variables, and more. Chemical reaction rates, are the rates of change in amounts or concentrations of either products or reactants. Concentration of solutions, surface area, catalysts, temperature and the nature of reactants are all factors that can influence the rate of reaction. Increasing the concentration of a solution allows the rate of reaction to increase because highly concentrated solutions have more molecules and as a result the molecules collide faster. Surface area also affects reaction rate because when the surface area of a reactant is increased, more particles are exposed to the other reactant.
