Investigating the Rate of Reaction Between Marble Chips and the Varying Concentrations of Hydrochloric Acid
Planning
Before starting the experiment I had to work out how much marble chips
would be needed and how much HCl would be needed. I decided that 20
grams of marble chips would be needed and I measured this on a pan
balance. The chips would have to be of medium size as from a previous
experiment done in class I realize that changing the surface area of
the marble chips would change the rate of reaction. I then used 100 cm3
of HCl and this would be the only variable that I will change.
I decided to use the concentrations of 0.5M, 1.0M, 1.5M and 2.0M
(1mole/dm). To make these different concentrations I added different
proportions of distilled water to the 2 molar HCl. For the 2M solution
I left the HCl alone, for the 1.5M solution I put 75 cm3 of HCl and 25
cm3
of distilled water. For the 1M solution I added 50 cm3 of HCl and 50
cm3 of distilled water, for the 0.5M solution I added 25 cm3 of HCl
and 75 cm3 of distilled water.
I then measured to see how long it would take to gain 100 cm3 of CO2
using a stopwatch and a gas syringe. To make sure the gas syringe is
working properly I must make sure that the clam is not on too tight or
it will affect the outcome of the results. To obtain the most reliable
results I will do each experiment three times.
[IMAGE]I predict that the high molarity concentration solution will
have a much faster rate of reaction than the weaker solution. I have
predicted this from my knowledge of a previous experiment and
scientific knowledge. The previous experiment I did was adding Sodium
Thiosulphate to Hydrochloric Acid Sodium Chloride + Sulfur Dioxide +
Sulfur + Water. We were going to see how long it takes to produce
enough sulfur to obscure a black cross under a beaker when we looked
We finally took 1ml of the 0.01% solution from test tube using the glucose pipette and adding it to test tube 4, we then used the H2O pipette and added 9ml of H2O to test tube 4 creating 10ml of 0.001% solution.
Each subsequent trial will use one gram more. 2.Put baking soda into reaction vessel. 3.Measure 40 mL vinegar. 4.Completely fill 1000 mL graduated cylinder with water.
3.) Divide your 30g of white substance into the 4 test tubes evenly. You should put 7.5g into each test tube along with the water.
Once the mixture had been completely dissolved, the solution was transferred to a separatory funnel. The solution was then extracted twice using 5.0 mL of 1 M
Put the amount of 0.1M cobalt (II) chloride hexahydrate that fills the end of a spatula into a test tube. Then add 2mL of 95% ethanol. Tap the end of the test tube to mix the solution and record the pertinent data in section 1 of the Data Table. Discard the solution in the appropriate container as directed to you by your lab instructor.

The Effect of Temperature of Hydrochloric Acid on the Rate of Reaction Between Hydrochloric Acid and Magnesium
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.
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.
