Marble Chips And Hydrochloric Acid Experiment

An investigation of the reaction between marble chips and hydrochloric acid.

Marble chips and hydrochloric acid experiment.

Marble chips placed onto pieces of paper. The rate of this reaction can be changed by changing the size of the marble chips. There are many variables that affect. Measured 5ml of hydrochloric acid in the 10ml measuring cylinders and placed into each beaker separately.

Using the apparatus shown the change in mass of carbon dioxide can be measure with time. In high concentrated acid the particles of the marble chip will move faster due to the more collisions between the particles of marble chips and the acid. I predict the higher the concentration of hydrochloric acid faster the reaction rate and more carbon dioxide will be produced as the time increases. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

Marble chips are mostly made up of calcium carbonate which is a alkaline compound. This is due to the collision theory. Being alkaline it reacts with hydrochloric acid to produce calcium chloride water and carbon dioxide. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.

Hydrochloric acid to react with the marble chips independent variable marble chips to react with the acid dependent variable stopwatch to accurately time the experiment spatula to handle the marble chips measuring cylinder to precisely measure out different concentrations of hydryochloric acid electric balance to measure the mass g of the marble chips bung. In the investigation i am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small large pieces of marble chips calcium carbonate and hydrochloric acid per minute. Measured out 1ml of water in a 10ml measuring cylinder and placed into the test tube labelled 2. Plugged in scientific scales and weighed out 1g of marble chips for each test tube.
