The Effect of Temperature on the Rate of Reaction Between Hydrochloric Acid and Calcium Carbonate
Hydrochloric Acid + Calcium Carbonate à Calcium Chloride + Carbon
Dioxide + Water
2HCl + CaCO3 Ã CaCl3 + CO2 + H2O
Aim.
To find out how the temperature of acid effects the rate of the
reaction between Hydrochloric Acid and Calcium Carbonate. I will do
this by changing the temperature of the Hydrochoric acid and keeping
the Calcuim Carbonate the same.
Theory.
By starting at a low temperature, the particles do not collide with
much energy giving a slow reaction. As you increase the temperature,
the particles should collide with more energy giving a faster
reaction.
The concentration of the acid, the time given inbetween each
measurement, the surface area of marble chips, the number of marble
chips, the volume of acid and the catalyst all affect the rate of
reaction.
The higher the concentration of acid, the more chance the particles
have of colliding.
The longer the time between each measurement, the longer time the
particles have to collide.
The bigger the surface area of marble chips, the more calcium
carbonate exposed to collisions.
The more marble chips, the more calcium carbonate the acid has to
react with.
The larger the volume of acid, the more acid the marble chips have to
react with.
Prediction.
I think by increasing the temperature of acid, the rate of reaction
will increase.
My graph should look like this
I will be investigating temperature as my variable. I chose
temperature because it will be the easiest to investigate with the
equipment in the school laboratories. I will change the temperature
using an ice bath or bunson burner.
I will measure the rate at which the water moves in the large
measuring cylinder. I will get the acid at 10ËšC using an ice bath, add
the marble chips then quickly put the gas tube and bung into my small
Investigating How the Concentration of Hydrochloric Acid Affects the Rate of Reaction with Calcium Carbonate
the acid was at 14 C the magnesium took 141 seconds to react and 27 C
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.
The Effect of Temperature on The Rate Of Reaction Between Magnesium And Hydrochloric Acid Planning I'm planning on investigating how temperature effects the reaction between magnesium and hydrochloric acid, the experiment will show whether the reaction will speed up or slow down with the change in temperature. Temperatures will range from room temp up until 70 degrees. The investigation will be a fair test because all quantities will remain the same for each test, each test will use the same amounts of hydrochloric acid and same size of magnesium, also the concentration of the acid will also not be changed.

Input variables In this experiment there are two main factors that can affect the rate of the reaction. These key factors can change the rate of the reaction by either increasing it or decreasing it. These were considered and controlled so that they did not disrupt the success of the experiment. Temperature-
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
Effect of Temperature on the Rate of Reaction between Sodium Thiosulphate and Hydrochloric Acid Investigation Chemical reactions are used in our everyday life, they literally keep us alive. They are used in food, respiration and everywhere else in the environment. A chemical reaction mainly occurs when reactants react together to produce a new product. The speed at which this reaction takes place is called the rate of reaction. The product produced has a number of particles in the solution that has formed from the reactants.
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.
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.
Investigating the Effects of Temperature on the Rate of Reaction between Magnesium and Hydrochloric Acid
An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid
My aim in this piece of work is to see the effect of temperature on the rate of a reaction in a solution of hydrochloric acid containing sodium thiosulphate.
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.
