Marble Chips And Hydrochloric Acid Experiment Surface Area Method

Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas.

Marble chips and hydrochloric acid experiment surface area method.

Smaller chips have a larger surface area. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. Measured out 1ml of water in a 10ml measuring cylinder and placed into the test tube labelled 2. To observe the effect of surface area particle size on the rate of reaction between marble chips calcium carbonate and hcl.

To investigate the effect of concentration of sodium thiosulphate in a reaction with hydrochloric acid. 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. 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. Hcl calcium carbonate calcium chloride carbon dioxide water.

And dilute hydrochloric acid calcium carbonate may be used in the form of marble chips. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. The surface area isn t always the same so even though the mass of the marble. Measured 5ml of hydrochloric acid in the 10ml measuring cylinders and placed into each beaker separately.

An investigation of the reaction between marble chips and hydrochloric acid. 2 to investigate the effect of temperature of sodium thiosulphate in a reaction with hydrochloric acid. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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.

Plugged in scientific scales and weighed out 1g of marble chips for each test tube. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. Marble chips placed onto pieces of paper. Calcium chloride solution is also formed.

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.
