Marble Chips And Hydrochloric Acid Experiment Surface Area Method

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

Marble chips and hydrochloric acid experiment surface area method.

Hcl calcium carbonate calcium chloride carbon dioxide water. Marble chips placed onto pieces of paper. 2hcl aq caco 3 s cacl 2 aq co 2 g h 2 o l the reaction rates of both large marble chips and small marble chips can be compared see below. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim.

Using the apparatus shown the change in mass of carbon dioxide can be measure with time. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. Plugged in scientific scales and weighed out 1g of marble chips for each test tube. Equipment list the equipment i will be using for this experiment to see how the surface area of marble chips caco3 affect the rate of reaction when placed in hydrochloric acid are 25 ml of hydrochloric acid 3g of marble chips graduated cylinder a stop clock test tube 250 ml beaker delivery tube scale ceramic mount and a plastic dish.

Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. To observe the effect of surface area particle size on the rate of reaction between marble chips calcium carbonate and hcl. Contains the marble chips hydrochloric acid and the water that will make the reaction. 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.

Smaller chips have a larger surface area. The surface area isn t always the same so even though the mass of the marble. 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. Measured out 1ml of water in a 10ml measuring cylinder and placed into the test tube labelled 2.

As the marble chips react with. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. Measured 5ml of hydrochloric acid in the 10ml measuring cylinders and placed into each beaker separately. Calcium chloride solution is also formed.

2 to investigate the effect of temperature of sodium thiosulphate in a reaction with hydrochloric acid.
