Marble Chips And Hydrochloric Acid Experiment Surface Area Method

Smaller chips have a larger surface area.

Marble chips and hydrochloric acid experiment surface area method.

Contains the marble chips hydrochloric acid and the water that will make the reaction. Hydrochloric acid marble chips the experiment 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 takes place. Add different sizes of marble chips solid crushed and powder concentration. 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.

Changing factors independent variables. Marble chips react with dilute hydrochloric acid to produce carbon dioxide gas. 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. 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.

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. Use a capillary tube to connect this flask to a measuring cylinder upside down in a bucket of water downwards displacement. Add different concentrations of hydrochloric acid method. Hcl calcium carbonate calcium chloride carbon dioxide water.

And dilute hydrochloric acid calcium carbonate may be used in the form of marble chips. To observe the effect of surface area particle size on the rate of reaction between marble chips calcium carbonate and hcl. Investigating the rate of reaction between marble chips calcium carbonate and hydrochloric acid aim. The surface area isn t always the same so even though the mass of the marble.

There are many variables that affect. An investigation of the reaction between marble chips and hydrochloric acid. Marble chips calcium carbonate caco 3 react with hydrochloric acid hcl to produce carbon dioxide gas. Calcium chloride solution is also formed.

Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. Finding the rate of reaction of marble chips and hydrochloric acid changing the surface area. Using the apparatus shown the change in mass of carbon dioxide can be measure with time. 2 to investigate the effect of temperature of sodium thiosulphate in a reaction with hydrochloric acid.
