Investigating The Rate Of Reaction Between Marble Chips And Hydrochloric Acid
Planning
I will use marble chips and different concentrations of hydrochloric
acid and water to see how it affects the rate of reaction. I will use
concentrations of 50cm3 using different volumes of water and acid.
Introduction
I am investigating how the rate of reaction between marble chips and
hydrochloric acid is altered when the concentration is changed. This
is the word equation for my investigation,
Calcium + Hydrochloric Calcium + Carbon + Water
[IMAGE]Carbonate Acid Chloride Dioxide
The symbol equation for my investigation is,
[IMAGE]CaCo3 + 2HCL CaCL2 + CO2+ H2O
Prediction
I predict that when I have a higher concentration I will have a faster
rate of reaction. Referring to Edexcel Science Revision Guide edited
by Mary James, the collision theory states that when there are more
particles, there are more collisions making the reaction faster (see
diagram). Also referring to Chemistry For You by Laurie Ryan, it
states "As you increase the concentration of the acid, there are more
acid particles in the same volume. Therefore there is a greater chance
of acid particles colliding, and reacting with more particles on the
surface of the marble." So, this means that the higher the
concentration of my acid the faster the reaction.
Method
I will weigh out one gram of marble chips using a balance and put it
in a conical flask and add to it a concentration of 50cm3 using water
and hydrochloric acid. I shall start by filling up a measuring
cylinder with water and putting it in a water bath so I can record how
much gas has been given off. I shall then put my one gram of marble
chips measured using in a conical flask then add to that my
concentration of hydrochloric acid and water, put on the bung and
start the stop clock. I shall record how long it takes for 25cm3 of
gas to be collected.
The reason I chose to do this investigation was because I have
This experiment will show how the temperature of water will affect how quickly a Alka-Seltzer tablet will dissolve. (Rowland) This experiment seemed appealing to me because it sounded interesting to experiment with chemical reactions. “How does the temperature of water affect how quickly an Alka-Seltzer tablet will dissolve?”

Investigating the Rate of Reaction Between Marble Chips and Hydrochloric Acid I am investigating the rate of reaction between marble chips (calcium
limestone chips, I will use 3g all the time and use 2 moles of acid.
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.
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.

Rate of Reaction Between Marble Chips and Hydrochloric Acid. The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) is used. There are many variables that affect the rate of this reaction such as the following. 1.
The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
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.
* Make sure each piece of potato is exactly the same size as the next.
3 cm of magnesium ribbon generally has a mass of 0.04 g and yields 40 cm3 of hydrogen when reacted with excess acid. 50 cm3 of 1M hydrochloric in this experiment is in excess.
It will be when there is too much HCl for the marble chips to dissolve
